Running Scared (Mysteries in Our National Parks, Book 11)

An invitation to study the declining bat population takes the Landons to Carlsbad Caverns National Park. With them is Sam, a young foster child. As Jack, Ashley, and Sam tour the underground wonders, a park worker suffers a seizure. The kids try to stay calm, but they know it will be a matter of only minutes before the candle burns down, leaving them in total darkness. It is definitely time to panic!
