Lunch Box Library — Andrew Gutelle

Here's the tastiest new idea to come along for kids' lunch boxes since the juice pack. Introducing Lunch Box Library, an ingenious way to enjoy reading that combines the old-fashioned pleasures of a cliffhanger with an innovative and irresistible design. Printed on a tear-off pad, each volume contains stories in serial form. Andrew Gutelle's 9 Puzzle Mysteries takes a different tack as kids help solve nine 10-part mysteries by cracking a different puzzle every day, including scrambles, cryptograms, math problems, and geography mazes.

Suitable for grades 3-5. 40,000 copies in print.
