“A highly topical yet deeply poignant examination of loss and grief, told with dark humour.”—The Daily Express
“A genuinely different take on the police procedural genre is hard to find, but Jo Callaghan has done it.

“Callaghan grounds her novel in real life, challenging her unusual team to investigate the unsolved disappearances of two students. The moral dilemmas created by artificial intelligence are brilliantly explored in this altogether very human novel.”—Sunday Times

The revelation of the full villainy involved in the two men’s disappearance is intriguing, but it is Kat—her personality, her relationship with her young son and her experience of loss—that really lifts this novel.”—The Literary Review
