A mind-bending Japanese horror from three-million-copy bestselling author Genki Kawamura, Exit 8 traps its protagonist - and the reader - in a looping underground world where every wrong move could mean never escaping.

A young man is riding the Tokyo subway when he receives a life-changing text message from his ex-girlfriend. He exits the train, but extraordinary things begin to happen, and he finds he cannot escape. Why is he trapped? Is it related to the text message he received? Will he solve the clues before it is too late?

The subway will loop endlessly unless he follows precise rules:

Do not overlook any anomaliesIf you find an anomaly, turn back immediatelyIf you do not find any anomalies, do not turn backGet out through Exit 8
Inspired by a cult video game and now adapted into an acclaimed film, Exit 8 is an innovative work of storytelling, and an ingenious locked-room mystery unlike any other.

Reviews

'Page-turning thrills and intriguing mystery ... a must-read for those who want to devour a story in one sitting' * Radio Times *
'Like Haruki Murakami at his finest, filtered through the fears and concerns of a whole new generation. Exit 8 takes tropes of gaming, anime and slacker fiction, mashes them together and strains the resulting blend into a shot glass' -- Richard Morgan * author of Altered Carbon *
