The Double-Dog Dare Challenge by Borders is a summer reading program for students under 12 years old. When you read 10 books, record those titles on the coupon form, and take that coupon form to a Borders, Borders Express, or Waldenbooks, you can trade your form for one of the remaining books available. This program runs from June 1 through September 5 only while supplies last. Here is a link to the available titles. Since these books are in a limited supply, you might want to use your time wisely and act on this program quickly.
