This summer, Barnes & Noble wants kids to stretch their imagination by reading some of their favorites books that inspire them to read fast, more and for longer than ever. Barnes & Noble’s Summer Reading Triathlon rewards kids (grades one through six) with a FREE book, after they’ve answered three questions in the Triathlon journal. Once it’s complete, young readers can take it to any participating location to pick out a well-deserved reward from a limited selection of children’s books. The program runs from May 17 to Sept. 6. Don’t forget, the bookstore also offers a FREE Kids’ Club with rewards and special offers — all year-long.
