Not as strong as The Hunger Games. For me, the pacing was a bit uneven and I was easily pulled away from the book after reading Part I. I finished that back in January and got back to it at the beginning of May, as I decided to clean up my GoodReads in-progress list a bit. Part II plodded a bit initially, but once the pace picked up, I blew through the rest of the book. 
 Even though the action is pretty good, without giving too much away, it's beginning to feel a bit samey. Looking forward to some resolution in the third book though, so I'll probably attack it right away.
