Some canyons hold deep, dark secrets... others should never be found.

Thirteen-year-old Sandy is just trying to enjoy a family vacation at Grover Canyon State Park with her younger brother, Pete. But when the two of them stumble across a hidden underground laboratory deep beneath the canyon floor, everything changes.

Inside, they find a corpse -- waxy, lifeless, and slouched at a reception desk like it's been waiting for something.

Terrified, they run. But the horror they've uncovered is only beginning.

Something has been awakened beneath Grover Canyon. And before the day is over, Sandy, Pete, and everyone else in the park will come face to face with a nightmare no one saw coming.

The Horror at Grover Canyon State Park is a standalone supernatural thriller in the Between Dark and Light middle-grade horror series.

Perfect for fans of Goosebumps, Small Spaces, and creepy mysteries for ages 10 and up.
