This was a lot of fun to read and I really want to play Warcross.  Marie Lu or someone make that happen!  Emika Chen is a hacker and bounty hunter.  Her father died when she was eleven and learned how to hack while in foster care.  She admires Hideo Tanaka, the creator of Warcross because he created Warcross when he was younger then she was and now at 21 owns his own company and a billionaire.  Emika’s life is not going so well.  She has less then $13 to her name and is facing eviction due to being 3 months behind in rent.  In a moment of desperation she hacked in during the opening ceremony of the Warcross Championships.  The next day she is on a plane to Tokyo and is hired by Hideo to track down a hacker named Zero.   Emika goes under cover as a player in the games so she can track down Zero and figure out who he is and what he is trying to do.  Emika is smart and quickly figures out that one of her own teammates is working with Zero.  She tells her findings to Hideo and because this is a YA novel, sparks fly because again YA novel, Hideo is hot!  I figured out who Zero was about halfway through the books but the beauty of it, it didn’t spoil the ending.  There are secrets in the game of Warcross that no matter how much a character opens up, we still don’t know all the facts.  This book was fast paced and full of twists and turns.  I do hope that in the next book that we get to know more about Emika’s teammates Asher, Roshan, Hammy and Ren because I feel like we just scratched the surface of who they are.  I’m really interested in seeing where Emika goes now that she knows the truth of what happened but is not really sure that it’s truly a bad thing.  I don’t want to say too much because it will spoil the ending but it will start some conversations.  So yes, go read it.
