OK -- The Nightbirds are Simta’s best-kept secret: Girls with a unique and powerful magic they can gift with just a kiss. Some would kill to possess them; the church would kill them outright. But protected by the Great Houses, the Nightbirds are well-guarded treasures. As this Season’s Nightbirds, Matilde, Æsa, and Sayer will spend their nights bestowing their gifts to well-paying clients. Once their season is through, they’re each expected to marry a Great House lord and become mothers to the next generation of Nightbirds before their powers fade away. But as they find themselves at the heart of a political scheme that threatens not only their secrets, but their very lives, their future suddenly becomes uncertain. When they discover that there are other girls like them and that their magic is far more than they were told, they see the Nightbird system for what it is: a gilded cage. Now they must make a choice—to remain kept birds or take control, remaking the city that dared to clip their wings.
