Casimira Aldora is a vampire and a sister of the Sun & Silver, an order sworn to preserving the peace between man and vampire. She is beloved by many, feared by others, but is widely regarded as the fiercest warrior in the human lands of Kilithgar; she is also the daughter of the vampire who once waged war on the human kingdoms and lands.

Thirty years ago, Overlord Sculdar Aldora led his army of vampires to the shores of Kilthgar, and the Dark Uprising began. Having a change of heart, Casimira left her father's war behind. Sculdar's forces were defeated and forced to retreat.

Since the end of the Uprising, there has been three decades of relative peace in Kilthgar, until one day, a village is attacked, its settlers slaughtered by a group of unknown vampires. Casimira is called upon to deal with the threat, but she soon learns that the attacks are far from random. Her journey leads her across the ocean, back home to a place where she hasn't been since quitting her father's war.

For the second time in her 134 years of existence, Casimira has to choose between her family and the very humans she has sworn to protect.

The novel includes adventure, betrayal, battle scenes, and the politics of a fantasy world where humans are trying to live with an enemy (vampires), in which they fear.
