Marina Cohen is an elementary school teacher in the York Region District School Board. She has a Master's degree in French Literature from the University of Toronto. The idea for her first novel, Shadow of the Moon, the story of boy/girl twins who must save the universe from darkness, brewed inside her for more than a decade before she began to write it. She completed the first draft in 2002--two years prior to giving birth to her own boy/girl twins. She often says, "I knew there was a reason this story was so close to my heart." Marina has since published the sequel, Trick of the Light (Vanwell, 2007) and has a Y/A thriller, Ghost Ride, coming out this fall with Dundurn Press.Marina has also written several non-fiction books for Crabtree Publishing including two books in a genetics series, two books in a graphic character education series, one book in a series on human migration and one in a math series. She has gained a profound respect for deadlines.
