Artemis Fowl

"The Twits" was a favorite of my younger kids. I recently read "The Lion, The Witch, and the Wardrobe" to them, and they loved it. Of course we had to make Turkish Delight after learning about it in the book. Other winners include: Redwall series, The Wingfeather Saga, Artemis Foul series, The Phantom Toll Booth. But 4 is a bit young for those.

This Perfect Day by Ira Levin (out of print, yet much more worthwhile in my opinion than other dystopic novels) Guns, Germs, and Steel by Jared Diamond The Books of the Fey by Kristine Kathryn Rusch Artemis Fowl series by Eoin Colfer The Deathgate Cycle by Tracy Hickman and Margaret Weis
