You might also want to add N.K. Jemisin's The Hundred Thousand Kingdoms to the list for this year, as it's been nominated (yay for new fandoms!). It's set in a fantasy world, but the protagonist and most of the main characters are chromatic, as is the author herself. :)

(Really hoping this one gets fic!)

ETA: Oh, and Nora Jemisin is a Brooklyn resident, so adding her should help with that last point in your post. (I think she grew up there, but you could ask her to be sure? She's on Twitter.)
