The Secret Box by Whitaker Ringwald

The Secret Box is a Junior Library Guild selection and the first in an irresistible middle grade series that will delight fans of Dan Gutman, Wendy Mass, and Trenton Lee Stewart.

What starts as a fun quest to open a mysterious birthday present quickly turns crazy and dangerous when Jax and her cousin Ethan discover themselves at the center of a special magical legacy. Soon they realize the secret box was not intended as a gift, but as call for help that they alone can answer.

Readers will love the page-turning mystery, hilarious girl and boy narrators, and clever incorporation of mythology—and lingering questions will leave them eager for more.
