Inheritance (Inheritance Cycle Book 4), Christopher Poalini
Fantasy. The fourth book in the Inheritance series, Inheritance is just as good as the first three (which are amazing). Before even thinking about reading this book, I suggest that you read the first three books, Eragon, Eldest, and Brisingr, as this book will be very confusing otherwise. There's a very clear definition of good and evil. 12+ for violence, NICE DRAGONS, and some cussing in the dwarf language (Barzul!).
