Need a little incentive to keep your child reading over the summer? Barnes and Noble is offering a free book for kids who answer three questions about the longest book, favorite series (Harry Potter, Junie B. Jones, Diary of a Wimpy Kid), and which book made you stretch your imagination. Personally, I love “Tuesday” by David Weisner. This wordless book lets you create your own story about why frogs might be flying around on lily pads.
