If you have a preschooler through 3rd grader, you should check out Mo Willems.  His books vary from engaging easy readers to humorous read aloud books.  A favorite in my family is The Pigeon Finds a Hotdog.  You can play games or look at books on his website.  The games are geared toward a younger audience.  His published books have a wider age range appeal.
