High above a jungle-planet float the last refuges of humanity—plant-made civilizations held together by tradition, technology, and arcane science. Here, architects are revered deeply, with humanity’s survival reliant on a privileged few. If not for their abilities, the cities would plunge into the devastating earthrage storms below.

Charismatic and powerful, Iravan is one such architect. His abilities are his identity, but to Ahilya, his archeologist wife, they are a method to suppress non-architects. Their marriage is thorny and fraught—yet when a jungle expedition goes terribly wrong, jeopardizing their careers, Ahilya and Iravan must work together to save their reputations. But as their city begins to plummet, their discoveries threaten not only their marriage, but their entire civilization.
