Olivia is grabbed from the street on her very first day of leaving home for university by two men wearing animal masks and is not seen again for several years. The graphic, gory descriptions of violence are definitely not for the faint hearted and are liable to give some people nightmares. There's a strong sense of menace and fear running throughout the book - a page turner if ever there was one. Could people be as horrible as this pair? One would hope not and it makes you aware of who you might pass in the street, of who might be watching you, which is a good thing. Make sure the windows are closed and the doors are locked! I'm afraid the ending was far too abrupt to be satisfying.
