DEBBIE DADEY taught first grade before becoming a librarian. It was while teaching that she first realized how much she wanted to write a book for reluctant readers. Her first book, co-authored with fellow teacher Marcia Thornton Jones, was the result of a very bad day. Since then, Debbie and Marcia have collaborated on more than 125 books with sales of over forty million copies. Their books include the Keyholders series, beginning with This Side of Magic and The Other Side of Magic. Debbie lives in Bucks County, Pennsylvania with her husband, three dogs, and three children.
