Branching Out
Deeply Rooted
Our son loved I Am Number Four, by Pittacus Lore as well. Each summer a new book in the series would come out, and he would request a trip to the book store to purchase it. Then we wouldn't see him for a few hours, while he finished it. He describes it as follows: 'Its about an alien race that has superpowers, and they are being hunted by another alien race. That was a fun series.'
