FEATURED ON 60 MINUTES and FRESH AIR

"So surprising and moving and true that I became completely unstrung." - The New York Times

Named a best book of the year by: The New York Times, NPR, TIME , Wall Street Journal , Boston Globe , Entertainment Weekly , Southern Living , Publishers Weekly , BookPage , A.V. Club, Bustle, BuzzFeed, Vulture, and many more!

JOHN GREEN , the acclaimed author of Looking for Alaska and The Fault in Our Stars , returns with a story of shattering, unflinching clarity in this brilliant novel of love, resilience, and the power of lifelong friendship.

Aza Holmes never intended to pursue the disappearance of fugitive billionaire Russell Pickett, but there's a hundred-thousand-dollar reward at stake and her Best and Most Fearless Friend, Daisy, is eager to investigate. So together, they navigate the short distance and broad divides that separate them from Pickett's son Davis.

Aza is trying. She is trying to be a good daughter, a good friend, a good student, and maybe even a good detective, while also living within the ever-tightening spiral of her own thoughts.

Excerpt provided by Syndetics

ONE At the time I first realized I might be fictional, my weekdays were spent at a publicly funded institution on the north side of Indianapolis called White River High School, where I was required to eat lunch at a particular time--between 12:37 p.m. and 1:14 p.m.--by forces so much larger than myself that I couldn't even begin to identify them. If those forces had given me a different lunch period, or if the tablemates who helped author my fate had chosen a different topic of conversation that September day, I would've met a different end--or at least a different middle. But I was -beginning to learn that your life is a story told about you, not one that you tell. Of course, you pretend to be the author. You have to. You think, I now choose to go to lunch , when that monotone beep rings from on high at 12:37. But really, the bell decides. You think you're the painter, but you're the canvas. Hundreds of voices were shouting over one another in the cafeteria, so that the conversation became mere sound, the rushing of a river over rocks. And as I sat beneath fluorescent cylinders spewing aggressively artificial light, I thought about how we all believed ourselves to be the hero of some personal epic, when in fact we were basically identical organisms colonizing a vast and windowless room that smelled of Lysol and lard. I was eating a peanut butter and honey sandwich and drinking a Dr Pepper. To be honest, I find the whole process of masticating plants and animals and then shoving them down my esophagus kind of disgusting, so I was trying not to think about the fact that I was eating, which is a form of thinking about it. Across the table from me, Mychal Turner was scribbling in a yellow-paper notebook. Our lunch table was like a long-running play on Broadway: The cast changed over the years, but the roles never did. Mychal was The Artsy One. He was talking with Daisy Ramirez, who'd played the role of my Best and Most Fearless Friend since elementary school, but I couldn't follow their conversation over the noise of all the others. What was my part in this play? The Sidekick. I was Daisy's Friend, or Ms. Holmes's Daughter. I was somebody's something. I felt my stomach begin to work on the sandwich, and even over everybody's talking, I could hear it digesting, all the bacteria chewing the slime of peanut butter--the students inside of me eating at my internal cafeteria. A shiver convulsed through me. "Didn't you go to camp with him?" Daisy asked me. "With who?" "Davis Pickett," she said. "Yeah," I said. "Why?" "Aren't you listening?" Daisy asked. I am listening , I thought, to the cacophony of my digestive tract . Of course I'd long known that I was playing host to a massive collection of parasitic organisms, but I didn't much like being reminded of it. By cell count, humans are approximately 50 percent microbial, meaning that about half of the cells that make you up are not yours at all. There are something like a thousand times more microbes living in my particular biome than there are human beings on earth, and it often seems like I can feel them living and breeding and dying in and on me. I wiped my sweaty palms on my jeans and tried to control my breathing. Admittedly, I have some anxiety problems, but I would argue it isn't irrational to be concerned about the fact that you are a skin-encased bacterial colony. Mychal said, "His dad was about to be arrested for bribery or something, but the night before the raid he disappeared. There's a hundred-thousand-dollar reward out for him." "And you know his kid," Daisy said. " Knew him," I answered. I watched Daisy attack her school-provided rectangular pizza and green beans with a fork. She kept glancing up at me, her eyes widening as if to say, Well ? I could tell she wanted me to ask her about something, but I couldn't tell what, because my stomach wouldn't shut up, which was forcing me deep inside a worry that I'd somehow contracted a parasitic infection. I could half hear Mychal telling Daisy about his new art project, in which he was using Photoshop to average the faces of a hundred people named Mychal, and the average of their faces would be this new, one-hundred-and-first Mychal, which was an interesting idea, and I wanted to listen, but the cafeteria was so loud, and I couldn't stop wondering whether there was something wrong with the microbial balance of power inside me. Excessive abdominal noise is an uncommon, but not unprecedented, presenting symptom of infection with the bacteria Clostridium difficile , which can be fatal. I pulled out my phone and searched "human microbiome" to reread Wikipedia's introduction to the trillions of microorganisms currently inside me. I clicked over to the article about C. diff , scrolling to the part about how most C. diff infections occur in hospitals. I scrolled down farther to a list of symptoms, none of which I had, except for the excessive abdominal noises, although I knew from previous searches that the Cleveland Clinic had reported the case of one person who'd died of C. diff after presenting at the hospital with only abdominal pain and fever. I reminded myself that I didn't have a fever, and my self replied: You don't have a fever YET . At the cafeteria, where a shrinking slice of my consciousness still resided, Daisy was telling Mychal that his averaging project shouldn't be about people named Mychal but about imprisoned men who'd later been exonerated. "It'll be easier, anyway," she said, "because they all have mug shots taken from the same angle, and then it's not just about names but about race and class and mass incarceration," and Mychal was like, "You're a genius, Daisy," and she said, "You sound surprised," and meanwhile I was thinking that if half the cells inside of you are not you, doesn't that challenge the whole notion of me as a singular pronoun, let alone as the author of my fate? And I fell pretty far down that recursive wormhole until it transported me completely out of the White River High School cafeteria into some non-sensorial place only properly crazy people get to visit. Ever since I was little, I've pressed my right thumbnail into the finger pad of my middle finger, and so now there's this weird callus over my fingerprint. After so many years of doing this, I can open up a crack in the skin really easily, so I cover it up with a Band-Aid to try to prevent infection. But sometimes I get worried that there already is an infection, and so I need to drain it, and the only way to do that is to reopen the wound and press out any blood that will come. Once I start thinking about splitting the skin apart, I literally cannot not do it. I apologize for the double negative, but it's a real double negative of a situation, a bind from which negating the negation is truly the only escape. So anyway, I started to want to feel my thumbnail biting into the skin of my finger pad, and I knew that resistance was more or less futile, so beneath the cafeteria table, I slipped the Band-Aid off my finger and dug my thumbnail into the callused skin until I felt the crack open. "Holmesy," Daisy said. I looked up at her. "We're almost through lunch and you haven't even mentioned my hair." She shook out her hair, with so-red-they-were-pink highlights. Right. She'd dyed her hair. I swum up out of the depths and said, "It's bold." "I know, right? It says, 'Ladies and gentlemen and also people who do not identify as ladies or gentlemen, Daisy Ramirez won't break her promises, but she will break your heart." Daisy's self-proclaimed life motto was "Break Hearts, Not Promises." She kept threatening to get it tattooed on her ankle when she turned eighteen. Daisy turned back to Mychal, and I to my thoughts. The stomach grumbling had grown, if anything, louder. I felt like I might vomit. For someone who actively dislikes bodily fluids, I throw up quite a lot. "Holmesy, you okay?" Daisy asked. I nodded. Sometimes I wondered why she liked me, or at least tolerated me. Why any of them did. Even I found myself annoying. I could feel sweat sprouting from my forehead, and once I begin to sweat, it's impossible to stop. I'll keep sweating for hours, and not just my face or my armpits. My neck sweats. My boobs sweat. My calves sweat. Maybe I did have a fever. Beneath the table, I slid the old Band-Aid into my pocket and, without looking, pulled out a new one, unwrapped it, and then glanced down to apply it to my finger. All the while, I was breathing in through my nose and out through my mouth, in the manner advised by Dr. Karen Singh, exhaling at a pace "that would make a candle flicker but not go out. Imagine that candle, Aza, flickering from your breath but still there, always there." So I tried that, but the thought spiral kept tightening anyway. I could hear Dr. Singh saying I shouldn't get out my phone, that I mustn't look up the same questions over and over, but I got it out anyway, and reread the "Human Microbiota" Wikipedia article. The thing about a spiral is, if you follow it inward, it never actually ends. It just keeps tightening, infinitely. I sealed the Ziploc bag around the last quarter of my sandwich, got up, and tossed it into an overfilled trash can. I heard a voice from behind me. "How concerned should I be that you haven't said more than two words in a row all day?" "Thought spiral," I mumbled in reply. Daisy had known me since we were six, long enough to get it. "I figured. Sorry, man. Let's hang out today." This girl Molly walked up to us, smiling, and said, "Uh, Daisy, just FYI, your Kool-Aid dye job is staining your shirt."  Daisy looked down at her shoulders, and indeed, her striped top had turned pink in spots. She flinched for a second, then straightened her spine. "Yeah, it's part of the look, Molly. Stained shirts are huge in Paris right now." She turned away from Molly and said, "Right, so we'll go to your house and watch Star Wars: Rebels ." Daisy was really into Star Wars--and not just the movies, but also the books and the animated shows and the kids' show where they're all made out of Lego. Like, she wrote fan fiction about Chewbacca's love life. "And we will improve your mood until you are able to say three or even four words in a row; sound good?" "Sounds good." "And then you can take me to work. Sorry, but I need a ride." "Okay." I wanted to say more, but the thoughts kept coming, unbidden and unwanted. If I'd been the author, I would've stopped thinking about my microbiome. I would've told Daisy how much I liked her idea for Mychal's art project, and I would've told her that I did remember Davis Pickett, that I remembered being eleven and carrying a vague but constant fear. I would've told her that I remembered once at camp lying next to Davis on the edge of a dock, our legs dangling over, our backs against the rough-hewn planks of wood, staring together up at a cloudless summer sky. I would've told her that Davis and I never talked much, or even looked at each other, but it didn't matter, because we were looking at the same sky together, which is maybe more intimate than eye contact anyway. Anybody can look at you. It's quite rare to find someone who sees the same world you see. Excerpted from Turtles All the Way Down by John Green All rights reserved by the original copyright owners.

Publishers Weekly Review

Voice actor Rudd sensitively portrays the protagonist of Green's latest novel, Aza Holmes, a 16-year-old with obsessive-compulsive disorder. Aza's mind is constantly crowded with anxiety and intrusive thoughts about germs and infection, which makes navigating the trials of high school no easy task. Luckily she has a best friend, Daisy, who helps keep her mind at ease. When the girls receive word that billionaire Russell Pickett left town to avoid arrest on criminal charges, and that there's a $100,000 reward for information about his whereabouts, Daisy convinces Aza that finding Pickett is just the distraction she needs. Along the way, Aza strikes up a friendship with Pickett's son, Davis, whom she had previously known at camp, and they form a bond despite their respective problems. Rudd speeds up the pace to show the overwhelming flood of thoughts that fill Aza's mind. She also captures the panic Aza feels and her frustrations with her condition as she becomes attracted to Davis. Rudd tops off the performance with a slew of memorable voices for the other characters-Aza's concerned mother, her coolly professional psychiatrist, and especially her chatterbox friend Daisy. Rudd's excellent, empathetic narration adds to the appeal of this psychologically complex, character-driven novel. Ages 14-up. A Dutton hardcover. (Oct.) © Copyright PWxyz, LLC. All rights reserved.

School Library Journal Review

Gr 9 Up-With her name, Aza's dad bestowed her with possibility: "It spans the whole alphabet, because we wanted to let you know you can be anything." Davis's father "made [him] a junior. Resigned [him] to juniority." The two teens have little in common-Davis is absurdly rich and lives in a staffed mansion, Aza is unsure how her mother will pay for college-but they share a brief past that overlapped at 11. They've also both lost fathers: Aza's is dead, Davis's is missing. Reunited when Aza and BFF Daisy trespass onto Davis's compound, Daisy is the first to declare "IT IS TRUE LOVE." Roadblocks are plenty (tidy endings are never a Green guarantee): Aza battles a debilitating fear of deadly bacteria that makes basic interactions challenging, Daisy has secrets she's willing to sell, Davis's brother Noah is not-so-slowly falling apart, and if the worst happens, a tuatara billionaire will become a thing. Narrator Kate Rudd takes Green's twisty, turny dramas in stride, crafting individuals-nerves for Aza, resignation for Davis, bouncing energy for Daisy, neediness for Noah-to create a resonating, unforgettable ensemble. -VERDICT Any new Green title means instant best seller; in preparation, libraries should acquire multiple copies in all formats.-Terry Hong, Smithsonian BookDragon, Washington, DC © Copyright 2017.

Booklist Review

*Starred Review* It's here: the eagerly awaited new novel by John Green, and not to milk the suspense it's superb. High-school junior Aza has an obsessive fear of being infected with the bacteria Clostridium difficile (C. diff), which can be fatal. Her fear has become obsession, plaguing her with intrusives, thoughts that take over her mind, making her feel that she is not the author of her own life. She does, however, have a life: her father is dead; her mother is a teacher; her best friends are Mychal, a gifted artist, and Daisy, a well-known Star Wars fan-fiction author. To their trio is added Davis, whom Aza had known when they were 11. Davis' billionaire father has decamped, pursued by the police, leaving Davis and his younger brother parentless (their mother is dead) and very much on their own. How will the friends cope with all this? And how will Aza cope with her own problems? Green, a master of deeply felt material, handles all of this with aplomb. With its attention to ideas and trademark introspection, it's a challenging but richly rewarding read. It is also the most mature of Green's work to date and deserving of all the accolades that are sure to come its way. HIGH-DEMAND BACKSTORY: The only question is, how many shelves worth of copies can your library fit? You'll need all of them.--Cart, Michael Copyright 2017 Booklist

Kirkus Book Review

Nerdfighter Green's latest takes readers through Indianapolis and the human biome.Aza Holmes doesn't feel like herself. But "if half the cells inside of you are not you, doesn't that challenge the whole notion of me as a singular pronoun?" When a local billionaireand the father of her childhood friend, a white boy named Davisdisappears, Aza (who seems to be white) and her BFF, Daisy Ramirez (who is cued as Latina), plot to find him and claim the reward, amid rumors of corruption and an underexplored side plot about semi-immortal reptiles. The story revolves around anxious Aza's dissociation from her body and life. Daisy chatters about Star Wars fan fiction (and calls Aza "Holmesy" ad nauseam), and Davis monologues about astronomy, while Aza obsesses over infection, the ever present, self-inflicted wound on her finger, and whether she's "just a deeply flawed line of reasoning." The thin but neatly constructed plot feels a bit like an excuse for Green to flex his philosophical muscles; teenagers questioning the mysteries of consciousness can identify with Aza, while others might wish that somethinganythingreally happens. The exploration of Aza's life-threatening compulsions will resonate deeply with some, titillate others, and possibly trigger those in between.Aza would claim that opinions about this book are unfairly influenced by "the gut-brain informational cycle," which makes it hard to say what anyone else will thinkbut this is the new John Green; people will read this, or not, regardless of someone else's gut flora.
