Here's a nonexhaustive list of authors of speculative fiction writing in or translated into English who are not of European descent.
Nationality is not considered. Many of the writers in question have non-speculative work as well, and in some cases the majority of their work may be non-spec. Magic Realism is considered as a genre unto itself, currently.
The original post where this list was compiled is over a year and a half old. It's here (http://matociquala.livejournal.com/1181728.html), and additions and emendations are encouraged.
(For all your Carl Brandon Society Awards-nominating needs. And also for the recommended reading of anybody who thinks the work of SFF writers of color began and ended with Octavia Butler and Samuel R. Delany.)
