Gideon Sterer is the author of many books for children, including the New York Times best-selling The Christmas Owl, cowritten by Ellen Kalish and illustrated by Ramona Kaulitzki. He grew up in the woods of upstate New York, where his parents owned a small zoo. After hours he would often run around and let the animals out of their cages. Who knows what sort of midnight mischief they got into? Gideon Sterer lives in Brooklyn.
