It's the seventh grade "outdoor education trip" to Lake Rescue! Adventure girl Charlotte's excited; city girls Katani and Isabel are not so sure. Of course, outdoor sports are right up Avery's alley, but bugs, snakes, and bears are so not up Maeve's.But no self-respecting BSG wants to miss out on adventures, and the week at Lake Rescue has more than its share: rock climbing, an unfortunate canoeing incident for a Queen of Mean, a hike that turns dangerous -- and the chance for one classmate to discover strengths she didn't know she had.
