Title: Kettly Mars
Content:  Mars was born on September 3, 1958, in Port-au-Prince. After completing a degree in Classics, Mars pursued training in administration – working as an administrative assistant for a number of years. Once in her thirties, Mars began to dedicate her time to writing. In a 2015 interview with Radio France Internationale, Mars said that once she was in her mid-thirties "everything that had constituted my life, until that point, started to lose its significance." Apart from being a mother, Mars says that her writing is "the most satisfying gift she has ever been given." The author of numerous collections of poems, short stories, young adult novels, and seven novels, Mars is one of the most active contemporary Haitian writers. Her work has appeared in various literary anthologies in both French and Kreyòl, such as the 2014 Anthologie bilingue de la poésie créole haïtienne de 1986 à nos jours edited and translated by Mehdi Chalmers, Inéma Jeudi, Jean-Laurent Lhérisson, and Lyonel Trouillot. In 2015, her novel Je suis vivant was awarded the Prix Ivoire pour la Littérature Africaine d’Expression Francophone at a ceremony in Abidjan in November.
Title: The Man Who Loved Mars
Content:  The Man Who Loved Mars is a science fantasy novel by American writer Lin Carter, the first in his Edgar Rice Burroughs- and Leigh Brackett-inspired series The Mysteries of Mars. It was first published in paperback by Fawcett Gold Medal in March 1973. The first British edition was published in hardcover by White Lion in August of the same year. It was reissued by Wildside Press in December 1999. The novel has also been translated into German. In writing the series, Carter deliberately depicted a Mars very different from that shown in increasingly detailed scientific research of Mars during the 20th Century; specifically, that scientists doubt that any kind of life can be found there. This makes the series more of a fantasy than a science fiction.
