She was shocked to learn that butterflies at the live exhibit near her home in Massachusetts had come from Central America. She and photographer Ellen Harasimowicz spent two unforgettable weeks researching the full story at El Bosque Nuevo, a butterfly farm in Costa Rica. The pair have collaborated on two other award-winning books for children. Visit Loree online at www.loreeburns.com. Ellen Harasimowicz is a freelance photographer in the Boston area.
