One of the book recommendations I had for this summer was Fablehaven by Brandon Mull. I handed the first book to Josh and he expressed his great displeasure at the assignment. (He HATES reading fiction, esp long-looking fiction!) However, a day or two into the book, he couldn't put it down, and has now flown through the four available books in the series (the final book has not been released yet) and is badgering me to hurry up and finish, too (I'm about to finish the 2nd book myself)! So, I just have to add my two cents that this series is fun and great for even reluctant readers. Just be prepared to buy your own -- the library copies are always gone!
Josh just walked by and I asked him to add a quick review:
"I love this series. It was really nicely written, sometimes you forget that it is just a story!"
