From its show-stopping opening scene, Keevil's tightly plotted page turner is full of momentum and unforgettable characters. Moving, profound and ultimately joyful, it turns on an exceptionally clever twist and is as revealing in its psychological acuity as it is in its portrait of organised crime. All it takes to change a life is a single moment. A random stabbing on a London bus leaves Eira stripped of a future that should have been hers and propels her into a life skewed out of all recognition. In Prague, the city where she and her husband got engaged, the city where now she flees to in her grief, a chance meeting leads to an intriguing proposition. There's a small job for someone like her: someone without a criminal record or personal connections; someone willing to take a minor risk. All she needs to do is pick something up, and drive back. Just once. Only ever once. Her mission takes her to a place where life is cheap and sordid deals are done. Risking her own life to save another, she must confront unspeakable evil and outrun those who would betray her.
