This book has very graphic sex scenes. It does not offend me but I think those scenes should at least drive the story. The sex scenes did not so they were just gratuitous sex scenes. The main character also thinks she is a murderer but keeps herself isolated so she does not actually kill anyone. She lives like this for years and there are some events that convince her that she must leave her apartment. She fulfills her self-imposed obligation without mass murder and seems to be cured by the end. It just is not a believeable story and the characters are superficial and predictable. It is not a bad book but it is not a great book either. Worth your time if you like “Girl” books.
