A subtle, spooky, headlong dash through the dark edges of romantic science fiction, a genre Kevin Brooks – with his usual delight in flouting convention – appears to have invented

Violently enjoyable

Original in its premise and captivating in its delivery. A gripping read

Sharp and precise . . . a meditation on the nature of humanity

An exciting on-the-run thriller . . . you'll be gripped

A compelling, compulsive, atmospheric story . . . The movie is already rolling in my head

Zips along at break-neck pace, each short, action-packed scene feeding into the next, ideal for teen readers with Playstation attention spans . . . McGann's direct, gritty style of writing certainly packs a punch
