Tick tock terror

Conor loves to climb.

So when the crusty old manager of a thrill ride based on Edgar Allan Poe's "The Pit and the Pendulum" challenges Conor to scale the ride in the dark of night and hide a package at the top, he foolishly accepts. But it isn't long before he realizes that he is now involved in something far more dangerous. What is in the package, and what does it have to do with Edgar Allan Poe? And why is the town bully so terrified of the old man? The more Conor learns, the deeper in trouble he gets.
