The Camp Fire Girls is a series of preteen fiction novels written by various authors from 1912 into the 1930s. The series began with The Campfire Girls of Roselawn, or, a Strange Message from the Air. An excerpt from the beginning of this book reads, As she worked, Bessie wondered why it was that she must always do the work about the house when other girls were at school or free to play. But it had been that way for a long time, and she could think of no way of escaping to happier conditions. Mrs. Hoover was no relation to her at all. Bessie had a father and mother, but they had left her with Mrs. Hoover a long time before, and she could scarcely remember them, but she heard about them, her father especially, whenever she did something that Mrs. Hoover didn’t like.
