Ann Carol Ulrich grew up (as Ann Schumacher) in a small town in Wisconsin. The Root Cellar Mystery was inspired by her childhood home in Monona, which had a root cellar underneath an addition to the family's house. She recalls that she and her friends used to explore it when they could get away with it. With her friends, she had a club which they called the P.E.D., and solving mysteries was part of their summertime fun. Nowadays, she writes novels and lives in Washington state. She has authored the Annette Vetter Adventure series for young adults, and has been a novelist since age 15. She continued to write romantic suspense and young adult novels and recently came out with her memoir about her adolescent years in Wisconsin and Michigan.
