About the Author

Margaret Peterson Haddix

I grew up on a farm outside Washington Court House, Ohio. As a kid, I liked to read a lot, and was also involved in 4-H, various bands and choirs (I played flute and piano) , church youth group, the school newspaper, and a quiz-bowl type team. I was pretty disastrous as an athlete, although I did run track one year in high school. After graduating from Miami University (of Ohio) , I worked as a newspaper copy editor in Fort Wayne, Indiana; a newspaper reporter in Indianapolis; and a part-time community college instructor and freelance writer in Danville, Illinois, before my first book was published. I've moved around a lot as an adult, having also lived in Luxembourg (during a college semester abroad) and in Clarks Summit, Pennsylvania. Several years ago, I moved back to Ohio with my husband and kids; we now live in Columbus, Ohio. My husband trains investigative journalists, and my kids are in high school, so there's always a lot going on around our house.
