Elle Cosimano grew up in the Washington, D.C., suburbs, the daughter of a maximum security prison warden and an elementary school teacher who rode a Harley. As a teen, she spent summers working on a fishing boat in the Chesapeake Bay. A failed student of the hard sciences, she discovered her true calling in social and behavioral studies while majoring in psychology at St. Mary's College of Maryland. Fifteen years later, Elle set aside a successful real-estate career to pursue writing. Her debut novel, Nearly Gone, was an Edgar Award Finalist, winner of the International Thriller Writers' Best Young Adult Novel Award, and winner of the inaugural Mathical Book Award recognizing mathematics in children's literature. Elle lives with her husband and two sons in Mexico, somewhere between the jungle and the sea. Website: www.ellecosimano.com. Twitter:@ellecosimano.
