High above a jungle-planet float the last refuges of humanity-plant-made civilizations held together by tradition, technology, and arcane science. In these living cities, architects are revered above anyone else. If not for their ability to psychically manipulate the architecture, the cities would plunge into the devastating earthrage storms below.

Charismatic, powerful, mystical, Iravan is one such architect. In his city, his word is nearly law. His abilities are his identity, but to Ahilya, his wife, they are a way for survival to be reliant on the privileged few.

Like most others, she cannot manipulate the plants. And she desperately seeks change. Their marriage is already thorny-then Iravan is accused of pushing his abilities to forbidden limits.

He needs Ahilya to help clear his name; she needs him to tip the balance of rule in their society. As their paths become increasingly intertwined, deadly truths emerge, challenging everything each of them believes. And as the earthrages become longer, and their floating city begins to plummet, Iravan and Ahilya's discoveries might destroy their marriage, their culture, and their entire civilization.
