In this National Parks Mystery, twelve-year-old Jack Landon and his younger sister Ashley travel with their wildlife biologist mom and photographer dad to Utah?s Zion National Park.

A string of life-threatening disasters keeps young readers turning pages as the fast-paced story builds to a heart-stopping conclusion.

When a cougar attacks a hiker in Mesa Verde National Park, the Landons have another mystery on their hands. Jack and Ashley are used to visiting parks with their wildlife veterinarian mother and photographer father, but this time their hands are full with a foster child called Lucky Deal. As Lucky and Jack become friends, Ashley becomes suspicious: What did Lucky take from the burn site? Who did she call in the night? In a midnight showdown at Spruce Tree House, Jack realizes there's more to fear than a killer cat. Cliff-Hanger weaves Native American folklore, natural science, and geography into a heart-pounding thriller. The afterword by Will Morris, Chief of Interpretation and Visitor Services at Mesa Verde, outlines the dangers of cougar attacks and the need to protect wild animals.

The following investigation leads readers on a trip through Morgan’s cyberworld connections and builds to a thrilling conclusion.
