Here’s the third book in the Monsterious series—terrifying tales that combine monsters + mysteries, perfect for fans of Goosebumps.

Twelve-year-old Tegan and his friends are excited to set out on a weeklong backpacking trip through the wilderness in Shadow Canyon, known for its vast forests and jaw-droppingly deep canyon. But after the group sets off on a little-used trail to visit a remote waterfall, they soon discover that the path markers they’ve been following have mysteriously disappeared, leaving them hopelessly lost.

As Tegan and his friends try to find their way back to civilization, they begin to notice strange things in the woods: small, oblong stones dotting the landscape in unexpected formations, tree roots that seem to be moving on their own, and creepy glowing eyes peering out of the shadows at night. Before long, they discover that something sinister stalks the forest—a creature with a hunger for human flesh. Can they make it out of Shadow Canyon alive?
