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

Twelve-year-old Josy suffers from an inexplicable illness. One day, she goes to her doctor's office and disappears without a trace.

Josy's father, Viktor, retreats to a remote island to cope with the tragedy. There, four years later, he is visited 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 is about a young girl with an unknown illness who has vanished 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 bring the truth to light. As the past is dragged back into the open, the sessions and their consequences become increasingly terrifying.
