The Inheritance Cycle by Christopher Paolini
Think your child could write the next Harry Potter? Maybe he can! Eragon, the first in this three-book series, was written when Paolini was only 15. The stories are set in the land of Alagaesia and focus on teenage Eragon, his dragon Saphira and their attempts at evading capture from the evil tyrant Galbatorix. In 2007, the author announced that there would be a fourth book to the series, so get started now and you and the kids could be caught up in time to read the final book upon its release.
