Not bad. Kept me up most of the night and I didn't start it until about 6pm on my home from work last night. I was worried because a few reviews likened it to Hunger Games, but it wasn't that. Yes, it is set in a dystopian future where people/society are segregated. Yes, there is some fighting and the main characters are teenagers with a female lead, but otherwise this felt like its own story. The plot wasn't obvious for me, which can sometimes happen with YA fiction. I enjoyed it, the story sucked me in and kept me in until the end.
