The startlingly powerful psychological thriller by international bestselling author Sebastian Fitzek.

Twelve-year-old Josy has an inexplicable illness. One day she goes to her doctor's surgery and disappears without a trace.

Josy's father Viktor withdraws to an isolated island in order to deal with the tragedy. It's there he is visited four years later by a beautiful stranger.

Anna Glass is a novelist who suffers from an unusual form of schizophrenia: all the characters she creates for her books become real to her. Her latest work features a young girl with an unknown illness who has disappeared without a trace...

Could her delusions really describe Josy's last days? Reluctantly, psychiatrist Viktor agrees to become Anna's therapist in a final attempt to uncover the truth. As the past is dragged back into the light, the sessions and their consequences become ever more terrifying.
