Andrea Beaty was raised in a small southern Illinois town, where her family ran a tiny grocery store. When she wasn't roaming the nearby fields with her brothers and sisters, she was reading Nancy Drew mysteries up in the branches of a maple tree. Andrea now lives outside Chicago with her family. She is the author of "When Giants Come to Play," illustrated by Kevin Hawkes, and "Iggy Peck, Architect," illustrated by David Roberts.
