As someone who is a fan of the Harry Potter series, it is impossible not to compare the two series when listening. The writing is excellent but doesn't have the polish of Rowling's writing. In some places the plot and characters are too predictable. However, my husband and I, both in our thirties, are still very intrigued and would recommend the book/CDs to anyone who likes fantasy. Also, the reader of the CDs just isn't as good as the reader of the Harry Potter CDs. Jim Dale, who reads the Harry Potter books for the CDs, is the best we've ever heard. Gerard Doyle, who reads the Eragon CDs, does do a good job but, again, it's just not as good. On the other hand, it's a good enough job that we are willing to pay for the CDs in order to listen to them! So, in summary, the book is a 4 star book and the reader is a 4 star reader!
