Twelve-year-old Jack and his almost-11-year-old sister Ashley find themselves wrapped up in a hair-raising mystery in Zion National Park in Utah.
The "Mysteries in Our National Parks" series treats intermediate readers to the adventures of brother-and-sister sleuths Jack and Ashley Landon.
Traveling with their mother, Olivia, a wildlife biologist, and their father, Steven, a nature photographer, the kids visit magnificent National Parks where they always seem to stumble upon a puzzle that only they can solve.
The Landon's adventures will keep kids on the edge of their seats while they learn about our country's natural heritage and the role we all have in understanding and protecting it for the future.
