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.
