Josy, a twelve year old girl, has an inexplicable illness and vanishes without trace from her doctor’s office during treatment. Four years later: Josy’s father, well-known psychiatrist Viktor Larenz, has withdrawn himself to an isolated North Sea island in order to deal with the tragedy. Until he’s paid a surprise visit from a beautiful stranger. Anna Glass is a novelist and she suffers from an unusual form of schizophrenia: all the characters she creates for her books become real to her.
