The crocodile bird, by Ruth Rendell

I loved this novel by Ruth Rendell. It's the story of 16 years old Liza, who has been kept isolated on the estate where her mother works. With a deep knowledge of literature and languages, she knows very little about the outside world. This begins to change when her mother is arrested for murder, and Liza runs off to be with the estate's gardener, with whom she has fallen in love. Over the next several months they live in his caravan working odd jobs, and she tells him the story of her life. As the tension builds, she begins to feel controlled by her boyfriend and she tries to think of a way out. Does she follow her mother's path, or forge her own? Very suspenseful and very well written.
