Got this one for my youngest son for Christmas. We love ourselves some Sci-fi. I wasn't quite able to get to it before I gave it to him (I got my copy at the library) but I wanted to read it anyway so we could talk about it. It is of course one of those very fun, page-turner type things. I breezed through it. I like all the figuring-out stuff and the character is charming (if a bit thinly developed–where did he come from? who is he really? why is he so disconnected from meaningful peer relationships?) But it was fun and I think my son will like it, so well done, me.
