'Devastatingly good. Tense as all the best thrillers are, but with an emotional heft that will leave you deeply moved. Will Dean's storytelling just gets better and better' JENNIE GODFREY

Three of them adrift on the narrowboat.
Mother, son, wickedness.

Peggy Jenkins and her teenage son, Samson, live on a remote stretch of canal in the Midlands. She is a writer and he is a schoolboy. Together, they battle against the hardness and manipulation of the man they live with.

Until, one day, Peggy assumes control, and their lives will never be the same again.

The author of the "master class in suspense" (Shari Lapena, Sunday Times bestselling author) The Last Thing to Burn returns with a high-tension thriller about a family's descent into darkness that is perfect for fans of Denis Lehane and Lisa Jewell.
