Author Kay Cassidy has gathered more than 100 authors of books for teens and tweens (grades 4-6) for her Great Scavenger Hunt contest. Writers like Kathi Appelt, Marion Dane Bauer, Pete Hautman, Kenneth Oppel, Susan Beth Pfeffer and Jennifer Ziegler have each created 10-question scavenger hunts for one or more of their books.

Scavenger hunts include questions like "What was the color of Moe's hideous car?" or "What is Gemma's favorite comfort food?" Every scavenger hunt also has a special note from the author.

As a "hunter," all you have to do is go to kaycassidy.com/hunt to find a list of participating books under "Trivia Challenges." Choose the one you want to read and print out the trivia challenge/scavenger hunt.

Titles include everything from "New York Times" bestsellers to Newbery Medal, Printz, National Book and Edgar award finalists, so you're sure to find something you'll love. New authors and titles from a variety of genres - fantasy, mystery, historical fiction, etc. - are added every month, so check back often.

After you've read the book and answered the trivia questions, take the completed page to any Worthington Libraries location. If your score is at least 8 out of 10, you'll be entered into Cassidy's monthly gift card drawing.

Because this is an ongoing contest, each month a new hunter will be chosen from among the entries to receive the $50 gift card.

When you win, Worthington Libraries wins, too. If your entry is chosen, the library gets a selection of scavenger hunt titles.

So pick a book and start hunting.
