A new romantic fantasy of magic, manners, and espionage that is also a "fast-paced thriller" (Carol Berg).

For the Darkborn, sunlight kills. For the Lightborn, darkness is fatal. Living under a centuries-old curse, the Darkborn and the Lightborn share the city of Minhorne, coexisting in an uneasy equilibrium but never interacting. When Darkborn physician Balthasar Hearne finds a pregnant fugitive on his doorstep just before sunrise, he has no choice but to take her in. Tercelle Amberley's betrothed is a powerful Darkborn nobleman, but her illicit lover came to her through the daytime. When she gives birth to twin boys, they can see, something unheard of among the Darkborn. When men come for the boys, Balthasar is saved by the intervention of his Lightborn neighbor-and healed by the hands of his wife, Telmaine. Soon he finds himself drawn deeper into political intrigue and magical attacks, while Telmaine must confront a power she can no longer keep sheathed in gloves, a power she neither wants nor can control.
