Saved by the Scouts by Erika Price

Erika takes her den of cub scouts on a hike and even after she warns them not to run, one of the boys does (of course) and ends up hurting himself. The other 8 year old kiddos, who have annoyed her with their messiness and rowdiness for months, apply their first aid knowledge gleaned from her, and are surprisingly helpful and thoughtful. Erika is an English professor at BYU.
