I think this was a really well-written YA novel, that dealt with some heavy topics - about identity and self-discovery, about friendship and growing up, about what we tell people & what we keep to ourselves - in well thought out ways. It was an intriguing premise - what if someone you thought had died, someone who knew you as a child, before you'd made so many 'improvements' and changes to yourself, suddenly reappeared? What would you have to face about your past, about yourself, about your relationships? I don't know: there was a lot here, and I liked that the author didn't hand out any simple answers to impossible questions (while at the same time providing a satisfying conclusion to the story). Good book: liked it a lot.
