With Dark Matter: A Century of Speculative Fiction from the African Diaspora, “editor Sheree R. Thomas sets out 'to offer readers an enjoyable entreé to the diverse range of speculative fiction from the African diaspora and to encourage more talented writers and scholars to explore the genre.' Her particularly rich and diverse collection accomplishes this and more with non-realistic fictions (and a few essays) by a cross-generational group of authors from the U.S., Canada, the Caribbean and Britain...Dark Matter also offers a great variety in the worlds imagined and in the storytelling approaches that bring us into those worlds.”
