I bought the book Eragon about a month ago. I am barley on the 5th chapter because it is too difficult for me to understand. The words the author chooses are too hard for my mind to comprehend. (mind you all that I am in my twenties and probably the only one out there that doesn't understand ) So i am not liking it too much. Maybe Eragon is getting more sales because Harry Potter got kids (and adults) reading again and we are all off keeping ourselves entertained while we wait for the next installment of Harry Potter. We all have to keep our minds away from the anxiety of awaitng book 6!!! And because Eragon is on the lines of Magic and dragons it kinda appeals to the kind of stories Harry Potter fans might be interested to read. Regardless, both series seem to be favorites for children and their content shouldn't be compared by book sales .
