"O" was one of the harder letters for me to find authors for. I could have used Octavia Butler, but I'm still saving her for another letter. Fortunately, I've read Who Fears Death, so I could use Nnedi Okorafor. She's written more works besides the one I mentioned above. (Who Fears Death won the World Fantasy Award and was nominated for the Nebula. Other works of Okorafor's have won the Wole Soyinka Prize for Literature in Africa, Macmillan Writers Prize for Africa, and the Carl Brandon Parallax Award.) She's written short stories and children's/young adult books. You can learn more about her and her work by visiting her website, Wikipedia, and Amazon.
Are you familiar with Okorafor's work, or can you think of more outstanding O authors? Please leave a comment.
