Donna Jo Napoli was born the youngest of four children in Miami, February 28, 1948, to an Italian-American family. After correcting an eyesight problem left undiagnosed until the age of 10, Napoli became an avid reader.[3] From then on she found solace in the escape provided by books, using reading as comfort during family troubles and instability stemming from her father's gambling problem.[3]
Napoli has dual citizenship in the U.S. and Italy. She is married and has five children.[4]
