Enhanced descriptions from Syndetics:

Four families wake up one morning in their caravans, next to their cars, on an ordinary campsite in southern Sweden. However, during the night something strange has happened. Everything else has disappeared, and the world has been transformed into an endless expanse of grass. The sky is blue, but there is no sign of the sun; there are no trees, no flowers, no birds. And every radio plays nothing but the songs of sixties pop icon Peter Himmelstrand.
As the holiday-makers try to come to terms with what has happened, they are forced to confront their deepest fears and secret desires, and in many cases expose the less appealing aspects of their character. Past events that they have tried to bury rise to the surface and take on a terrifying phyiscal form.
Can any of them find a way back to reality?
I Am Behind You is a compelling, eerie new novel from the internationally bestselling author of Let the Right One In .

Excerpt provided by Syndetics

We know a person by their faults and defects. The missing cog defines the machine; a dissonant chord makes a song fall apart--or makes it interesting--and our defects drive us to great achievements or despicable deeds. You could say that this is what makes us human, imperfect and fascinating. You could also say that it makes us into reptiles, dragging ourselves along between heaven and earth, searching for something to fill the void.  Excerpted from I Am Behind You by John Ajvide Lindqvist All rights reserved by the original copyright owners.

Library Journal Review

When Isabelle's daughter wakes her up because she cannot find the bathroom outside their caravan, Isabelle thinks someone has played a horrible trick on them and the other three families camping nearby. But the campground has suddenly vanished, and family is parked on green grass that stretches as far as they can see. The sky is bright blue, but there's no sun. In fact, there is nothing at all to show them where they are: no trees, no buildings, no animals, no civilization. Most electric devices do not work, and the radios only play 1960s pop singer Peter Himmelstrand. As the story unfolds, the four families work together to discover where they are and if a way out is possible. Dark fears and desires and past events the characters have tried to bury are coming to light under the bright sunless sky, and there may be no way to survive it. VERDICT Swedish sensation Lundqvist's (Let the Right One In) twisting journey into the dark corners of the mind is true psychological horror. It will keep entranced and shocked readers guessing until the very end.-Kristi Chadwick, Massachusetts Lib. Syst., Northampton © Copyright 2018.

Publishers Weekly Review

Four families and their vacation caravans are somehow transported into a seemingly endless grassy meadow in Lindqvist's ambitious and frustrating novel of cosmic horror, the first of a projected trilogy. Their world now includes a bright sky, no sun, a lot of grass, three married couples of various degrees of happiness, two friends who are inching toward romance, two children, one cat, one dog, and whatever was in the caravans when they arrived. GPS maps show them in places they cannot possibly be, such as on roads that ceased to exist years ago. The radio works, but plays only songs written by Peter Himmelstrand, a real-life 1960s Swedish pop star. (In Sweden, the title of the novel is Himmelstrand.) Unsurprisingly, tensions in the group are high, especially since unpleasant, elderly Donald has a gun, and Molly, one of the children, is a budding psychopath. The characters, the group dynamics, and the unfolding mystery of what's going on and why are well-depicted and engrossing, but the ending peters out in a futile attempt to remain emotionally satisfying while still leaving most events unexplained. A future book may shed more light, but the first installment makes it difficult to maintain enough investment in the story to want more of it. Agent: Anneli Hoier, Copenhagen Literary (Sweden).

Booklist Review

In an exercise recalling Stephen King's Under the Dome (2009), Lindqvist, an author capable of imbuing his terrifying tales with heavy doses of emotion, crash-lands characters into an absurd situation and then lets chaos reign. Four families go to bed in their camping trailers, only to awaken with the campsite, as well as the rest of the world, utterly gone, replaced by an endless horizon of green grass. Former soccer star Peter and his model wife, Isabelle, were already at each other's throats. Stefan, Carina, and their son, Emil, are simply not cut out for such stress. Violent lout Donald and his numbed wife, Majvor, don't care what happens to the others. And elderly gay couple Lennart and Olof are concerned about Peter and Isabelle's daughter, Molly, who seems to be channeling some nefarious force. The explicitly supernatural elements lurking monsters having something to do with past traumas never satisfyingly coalesce, but when Lindqvist channels the classic Twilight Zone episode ""The Monsters Are Due on Maple Street,"" showing how quickly humans will turn on one another, the results are chilling.--Daniel Kraus Copyright 2018 Booklist
