Octavia Estelle Butler was an American science fiction writer, one of very few African-American women in the field. She won both Hugo and Nebula awards. In 1995, she became the first science fiction writer to receive MacArthur Foundation “Genius” Grant.
Butler is well known for her “Patternist series,” “Xenogenesis Trilogy,” and the “Parable of the Sower Series.” The first book which she wrote for the ‘Patternist’ series, ‘Patternmaster’ (1976), is actually the last in the internal chronology of the series. In fact, most of the ‘Patternmaster’ novels were written and published out of sequence. Her ‘Xenogenesis’ series was released in 2000 as the single volume, “Lilith’s Brood.” The four novels in Butler’s “Patternist series” other than “Survivor” will be released in 2007 as the single volume, “Seed to Harvest.”
