p.s. We enjoyed The Hunger Games series, but it got really political in the end. It was sneaky using such an interesting premise to lure me into reading about politics, which I would never do voluntarily, lol... It can be violent and a little depressing at moments, so if you don't want to cry, it might not be what you are looking for.
Instead, maybe the Uglies series by Scott Westerfeld- 4 books called Uglies, Pretties, Specials, and Extras. I thought Extras was one I could give or take but the first 3 were awesome!
And, my teenage daughter enjoyed them all too!!
