A therapist mourning his missing daughter encounters a patient with dangerous secrets in this hard-hitting psychological thriller from international bestseller Sebastian Fitzek.

The startlingly powerful psychological thriller by international bestselling author Sebastian Fitzek. Now adapted into a compelling TV series from Amazon Germany. Four years ago Josy, the 12-year-old daughter of well-known psychiatrist Viktor Larenz, disappeared without trace: no witnesses, no demands, no body. In the aftermath of Josy's disappearance, Viktor's marriage broke down and he withdrew to a remote North Sea island to find peace and to heal. Now, that peace has been shattered by the arrival of Anna Glass, a novelist: beautiful, enigmatic, schizophrenic. Anna's schizophrenia is rare and unusual: the characters she creates for her books become real to her. And she has started writing about a young girl who disappeared without trace... Could Anna's delusions describe Josy's last days? The prospect of uncovering the truth lures Viktor into becoming Anna's therapist. As the past is dragged back into the light, their sessions and the consequences become ever more terrifying. Reviews for Sebastian Fitzek 'Fitzek's thrillers are breathtaking, full of wild twists.' Harlan Coben 'Fitzek is without question one of the crime world’s most evocative storytellers.' Karin Slaughter '[A] superior German thriller.' Daily Telegraph
