For centuries, she has been a ghost in the timeless streets of Prague, a creature of shadow and solitude, content to watch the fleeting lives of mortals from a distance. But when the last tie to her ancient vampiric lineage is severed, a terrifying and unwelcome change begins-the curse that granted her immortality is fading.

A single, impulsive act of justice-saving an innocent woman from a brutal predator-drags Liliana from her isolation and into the messy, violent world of human affairs. The act puts her on a collision course with a weary detective who refuses to believe in monsters, and in the crosshairs of a secret society of powerful men whose depravity rivals her own.

Hunted by forces she doesn't understand and plagued by a new, terrifying vulnerability, Liliana discovers that the greatest threat may not be the enemies closing in, but the unfamiliar humanity awakening within her. To protect the innocent, she must confront the legacy of the monster who sired her and decide what is more dangerous: the monster she was, or the woman she is becoming.
