The Black Tides of Heaven is one of a pair of unique, standalone introductions to JY Yang’s Tensorate Series, which Kate Elliott calls “effortlessly fascinating.” For more of the story you can read its twin novella The Red Threads of Fortune, available simultaneously.

Mokoya and Akeha, the twin children of the Protector, were sold to the Grand Monastery as infants. While Mokoya developed her strange prophetic gift, Akeha was always the one who could see the strings that moved adults to action. While Mokoya received visions of what would be, Akeha realized what could be. What’s more, they saw the sickness at the heart of their mother’s Protectorate.

A rebellion is growing. The Machinists discover new levers to move the world every day, while the Tensors fight to put them down and preserve the power of the state. Unwilling to continue as a pawn in their mother’s twisted schemes, Akeha leaves the Tensorate behind and falls in with the rebels. But every step Akeha takes towards the Machinists is a step away from Mokoya. Can Akeha find peace without shattering the bond they share with their twin?

San Francisco in 1940 is a haven for the unconventional. Tourists flock to the cities within the city: the Magic City of the World’s Fair on an island created of artifice and illusion; the forbidden city of Chinatown, a separate, alien world of exotic food and nightclubs that offer “authentic” experiences, straight from the pages of the pulps; and the twilight world of forbidden love, where outcasts from conventional society can meet.

Six women find their lives as tangled with each other’s as they are with the city they call home. They discover love and danger on the borders where magic, science, and art intersect.

Inspired by the pulps, film noir, and screwball comedy, Passing Strange is a story as unusual and complex as San Francisco itself from World Fantasy Award winning author Ellen Klages.
