I enjoyed this book, I read this for bookclub as our sci-fi pick and I thought it was a good time. 

I don't think it was that deep and as a YA I did find parts of it a bit irrelevant to me, there was lots of overcoming bullying with more violence which I felt uncomfortable with. 

It was a fast paced book and I flew through it, I felt that it dragged a little in the middle, and became a little repetitive by the end but overall a fun war games book.
