Penelope Prescott, 16, longs for excitement. She meets Kelvin Sutton, 17, an adventurer at heart, with a strong Christian faith, and they become fast friends. So, when they, along with a couple of cute boys, find an abandoned manor in the woods, it seems like the perfect place to party. But they soon discover that someone else is using the mansion for sinister purposes when they uncover a chemical spill, and a probable murder, both of which plunge them into peril unlike any danger they've ever known. Will they live long enough to tell anyone?
