HANNAH BONNER was born and raised on the Spanish island of Mallorca, in an American household. She attended Spanish schools through high school, and then went to Oberlin College in Ohio, where she studied biology and art. Over the years she managed to bring her two loves together by specializing in natural science illustration. In 2000 she illustrated the best-selling Scholastic Science Dictionary. Shortly thereafter she began writing as well as illustrating. This is her third book for National Geographic as both author and illustrator.
