Very believable, totally gripping stuff. The characters are verywell-written, and you do find yourself wanting to know if Natalie doespass all the tests by the end of the book. There haven't been many booksthat I haven't been able to put down, but this was one of them - I wasstill reading avidly in the wee small hours of the morning! Rather thanbeing over the top in the sexual scenarios, it's full of situations thatare actually possible, and that real people would be involved in, whichsets it apart from other books of this genre that I've read. A greatread, thoroughly recommended!
