The Mark of the Scorpion

When your parents surprise you with a solo trip to visit your cousin in the Desert Southwest, you pack your bags and prepare for adventure. Spending time exploring the sun-baked scenery sounds like a perfect vacation.

On a hike through Vulture Point Park, you’re stunned to discover graffiti scrawled across the park’s iconic rocks. Each occurrence of vandalism is marked by an ominous symbol of a scorpion. Authorities believe the graffiti is destructive but not dangerous—the work of a few delinquent teens—but you’re not so sure. The more clues you uncover, the more convinced you are that something major is about to go down. You’re pulled into a twisted plot that threatens to destroy the entire park—and take countless lives. The stakes are high, the danger is real, and the countdown has begun.
