The new novel Saving The Pearls: Defending Eden sounds like something that someone made up as a prank. Victoria Foyt's self-published novel takes place in a world where, due to global warming, most white people are dead. The world is ruled by black people, called "coals" in the book. The remaining white people, called "pearls," are oppressed by the "coals." But apparently this book is real, and its author chose to promote it with a video showing a white person in blackface. The internet, not surprisingly, was not amused.
Update: Weird Tales has apologized and backtracked.
