I really liked this one. I've never really read a thriller/mystery before and I really enjoyed it. It starts off grabbing you and doesn't let go. It's relentlessly fast-paced, full of twists and turns that keep you on the edge of your seat. That Panda and Ocie are bi-racial was something I appreciated. 
 The thing I really liked was that Panda knows by the end she isn't a good guy. She may have had an awesome blog and done a good thing for some people, but she also ruined some lives. She recognizes that and is ready to own up to her actions. The question of whether or not Panda really is good or had good intentions would be a great point of discussion. 
 I'd recommend this book for teens who like super fast-paced mystery/thrillers and characters of questionable morality.
