Specials by Scott Westerfeld. It was an okay book...Here's the review I wrote on it at http://www.goodreads.com/
This book took me a while to get into but once I got into it I couldn't put it down. The future aspect of this book was kind of weird at times but I loved the ending. I can't wait to start Extras.
I give it 3 out of 5 stars.
