Told in two POVS, Fireborne tells the story of two characters who couldn't be more different, the same in only their desire for the position of first rider. The world building is distinct and done to a high quality, something that I appreciated a lot while reading.
I enjoyed the dragon element of the book, but it could pretty much be substituted with horses without much change to the plot. Eragon comes to mind when I think about dragon-human bonds, but don't come looking here if that's the kind of dragon content you seek. This book is more focused on discussions involving politics and ethical decisions. If you enjoy books where characters are forced to make difficult and tough choices, this is the right book for you.
