Fire  - Kristin Cashore As others have commented, this book, the prequel to Graceling, is much more adult in tone, and in my opinion a better book. Fire is a wonderful protagonist and I really loved the way Cashore connected the world from Graceling with the world in this book. The story is a bit slower off its feet than Graceling, but the story on the whole is more robust and more satisfying in its conclusion.
