Mr. Turner's sophomore science class is a favorite among his high school students, with lively experiments and funny discussions-and he has made science even more exciting by awarding a seat on the school bus going to the Ghost Creek Day Camp for anyone who scores 100% on their final exam. Ghost Creek offers ATVs, hiking trails, archery, and more-with a competition to win two tickets to any venue, athletic or musical program the winner desires. It's what students work toward all year. Sarah has earned 100% on her final exam, and she and her friends are packed up and ready for fun! But first they have to survive the flash flood that tips over their school bus...and this is only the beginning of Sarah's summer adventures.
