The first of these, Divergent, I remember very little about, except for liking it quite a lot at the time. So, I won't vouch for its literary quality, but I do know it holds a higher standard of morality than most dystopian fiction, including The Hunger Games (if not a comparative level of originality.)
The other, The Book Thief, was very original, though I felt the ending lacked closure. I think I might like it better as a movie than a book, though I have an instinctive dislike of child actors (excepting Christian Bale, who shoots child acting into the stratosphere). I review it here.
