Broken

A writer wakes one night to find a strange man in her bedroom. He is a character she has invented, but not yet used, and so desperate is he to have his story told that he has resorted to breaking into her house. She creates him for Alvar Eide, a quiet, middle-aged man whose life is carefully designed to avoid surprise, but when a young heroine addict comes into the gallery where he works, Alvar's life is changed forever and his inventor realises that she cannot control the character she has created.
The result is a superb novel that plays with the boundaries of fact and fiction.
