Caroline Stevermer grew up miles from anywhere on a dairy farm in southeastern Minnesota. She has a sister and two brothers. After high school, she attended Bryn Mawr College in Pennsylvania, where she earned a B.A. degree in the history of art. She knew she wanted to be a writer when she was eight years old. She began by writing stories in her school notebooks. (They were not good. Many were not even finished. She persisted.)

By the time she graduated from college, she knew she would need to earn money in other ways, but she kept on writing. Her first professional sale was published by Ace in 1980. In the years since, she has had a variety of jobs and kept on writing. She likes libraries and museums. Her favorite painter is Nicholas Hilliard. Her favorite writer is Mark Twain. She lives in Minnesota.
