Thank you for the suggestions. The Amulet and A Wrinkle in Time look like they would be terrific reads, but they both look like they would be too scary for both boys at this point. Zita the Space Girl was definitely on the line in terms of level of comfort.

Anything more lighthearted would be great at this point. It doesn't have to be great literature - after all, we tear through about 5-6 books a day (some are still picture books)!
