The Black Tides of Heaven and The Red Threads of Fortune, by JY YangRead about the other entries on the list.
In the first two of Yang’s Tensorate novellas, we follow twins Mokoya and Akeha through the years spent navigating their tumultuous world, Ea. By no stretch of the imagination are they identical, growing in divergent ways, developing distinct powers, and choosing sharply different life paths. Moreover, in a world in which gender is chosen at maturity, gifted soothsayer Mokoya opts to become female, while machine-minded Akeha becomes male. Both twins attempt to influence and shape the world in their own ways, and their eventual estrangement may be bridged only by rebellion.
