The sixth and seventh graders at Joyce Kilmer Middle School are spending a week at Camp Einstein, a science camp in the woods. Jenny can't wait--this will be even better than sleepaway camp, since her friends will be there, too! Unfortunately for Jenny, she, Chloe, and Sam have to share a cabin with Pops Addie and Dana. Things go from bad to worse when Jenny is paired with Addie for trust exercises. How will Jenny and her friends survive their night hike with the Pops?
