Hell's Serpent (Paperback) (ISBN-13: 9781923165649)

A group of college friends ventures into the wilderness to celebrate the end of the semester. But when they arrive at their favorite campsite, they're stunned to find the landscape transformed-sunken nearly a hundred feet into a massive crater.

Suspecting the recent drilling in the area might be to blame, they begin to investigate. But something far older and far more dangerous has stirred beneath the earth.
