Descend into underground danger in this third book in New York Times bestselling author Christopher Pike's Spooksville series.
There is a famous cave located just outside of Spooksville. A lot of stories surround the dark place: scary ones as well as exciting ones. Adam decides to explore the cave with his friends, Watch, Sally, and Cindy. But the moment they go into the cave, the entrance closes behind them. They are trapped. In the dark.
They walk deeper into the cave, frantically searching for a way out. The batteries in their flashlights begin to run low. Then they realize something is following them. Something that has been in the cave for a long time. Something big, black...and hungry.
