Care Santos was born in 1970 in Mataro, a city just north of Barcelona, Spain. She began writing at eight years old, and never wanted to be anything but a writer. At fourteen she won her first writing competition, and at twenty-five published her first book, a collection of short stories. Since then, she has published six novels, six collections of short stories, two collections of poetry, and a great many books for children and young adults. Santos is one of Spain's most read children's book authors, and her work has been translated into German, French, Italian, Portuguese, Lithuanian, and Korean. She's the founder of the Association for Young Spanish Writers, and served as the organization's president for eight years. Currently, she gives literary workshops throughout Spain and the Americas, and serves as a literary critic for the national Spanish newspaper El Mundo. Santos dedicates the rest of her time to raising her three children who, in the author's own words, "are [her] greatest works of art." Her latest novel, Habitaciones Cerradas, was published by Planeta in 2011.
