I think this book deserves a solid 3.7 stars. I suppose I'm just not in the mood for series as of late. In my opinion, it's a bit tiresome to wait for the next book in a series that is just so-so. I'll probably read the next book when it comes out, but hopefully I won't have forgotten too much by that point.
Overall, it was an enjoyable read. There was lots of action and I liked the different powers/abilities. They were constantly on the move and there were times when I was surprised by the brutality of Alexandra Bracken's descriptions. Unfortunately, the ending was a bit predictable and lessened the impact (at least for me).
