"A slippery page-turner that's as profoundly beautiful as it is totally unhinged."—Rachel Harrison, New York Times bestselling author of Play Nice and So Thirsty

"Intense, irreverent, surprising, raw." —Natalia Theodoridou, author of Sour Cherry

"Fans of Yellowjackets will eat up this queer, psychologically chaotic tale. A decadently bizarre novel for fans of queer survival stories."—Kirkus Reviews, starred review

"Van Os’s equally eerie and tender first novel is a smart and off-kilter exploration of survival and queer intimacy... Van Os skillfully captures the rising panic of getting lost in the woods, calling to mind survival horror like The Blair Witch Project and Yellowjackets, while her gloopy, visceral descriptions of decay are reminiscent of the kind of bodily unease relished by Ottessa Moshfegh... This is sure to win van Os many fans." —Publishers Weekly

"Raw and heartrending, Decomposition Book will seduce you with its tender yet terrifying love story. Horror fans will delight at the gruesome premise while other readers will be enchanted by van Os’s deft prose and poignant emotional arcs. This is a masterclass in horror." —Kylie Lee Baker, author of Bat Eater and Other Names for Cora Zeng

"Told with delicious humor and surprising grace, Decomposition Book is a compulsively readable story of courage, of desire, of unrelenting love, and of what is left when one's humanity is stripped away—whether by loss, obsession, or rot. A marvelously strange novel, both unprecedented and unforgettable." —Kerry Cullen, author of House of Beth

"I'm obsessed. Sara van Os's narrative voice is so compelling and unique, I was eager to follow it to every deranged, dark place it wanted to take me. Unrelentingly entertaining, Decomposition Book is a wild ride you don't want to miss." —Tatiana Schlote-Bonne, author of The Mean Ones

"Funny, poignant, and grotesque, Decomposition Book is impossible to put down. In two tragic love stories, Sara van Os pulls back the skin of her characters to reveal the humanity beneath—bugs and all." —Maggie Su, author of Blob: A Love Story

"Swiss Army Man meets Yellowjackets in this gorgeous and grotesque debut. Weird, haunting, funny, deranged, and disorienting, Decomposition Book delivers an unforgettable story with one of the most captivating narrative voices I’ve read in a while. A pitch-dark delight." —Megan Collins, author of Cross My Heart and The Family Plot

"You wouldn't think a tale about a woman's rotting corpse could be so irreverent, darkly funny, poignant, and heartfelt. Decomposition Book shows that Sara van Os is one to watch, with this outrageously readable Yellowjackets-inflected lost-in-the-wilderness horror story." —Ally Wilkes, author of All the White Spaces

"So sharply written and darkly funny, this is going to be one of my favourite reads of the year—I’m already recommending it to everyone!" —Lisa Hall, author of The Woman in the Woods

"At once tender, brutal, and beautifully bizarre, Decomposition Book is an unmissable tale of isolation and homecoming that will bring you back to life." —Tobi Coventry, author of He’s the Devil
