So glad you have 'fessed up on the main thread, Psycho
This has been on my "want-to-read" list for aaaaaaages so I was so pleased to get it, and it was a really, really good read.
I was particularly impressed at the way the author makes Tess a believable teenager. Lesser writers might have been tempted to turn her into a complete saint, but I wanted to slap her for most of the book - the monumental self-obsession of a teenager focused through the prism of imminent mortality is a pretty lethal combination.
Worth it for the last 50 pages alone - I thought this had the most incredible ending of any book I have ever read and I was sobbing buckets.
