Eragon (Inheritance, Book 1)
Eragon is quite a derivative book. While there are certainly some original ideas in the book, Christopher Paolini seems to have relied very heavily on JRR Tolkien's "The Lord of the Rings" and Anne McCaffrey's "Dragonriders of Pern" series for source material. I personally dislike this book because, while material from "The Lord of the Rings" is used throughout the entire book, Mr. Paolini has removed much of what made LOTR a really great book (at least in my opinion). He has removed all of the underlying current of Christian worldview and morals which Tolkien incorporated into his book. I do not recommend this book.
