Retribution - Chronicles of the Uprising, #5

Immortality is never guaranteed... As much as Mira dreams of a simpler existence, blood and violence are her way of life. Former gladiator turned freedom fighter, she has carved a trail from New Haven to Caldera Grove and back, freeing her people, the vampires, from enslavement by the humans. But with victory almost within reach, a new and powerful enemy emerges. One who'll be satisfied with nothing less than complete subjugation-or destruction-of all supernat-ural beings.
With a secret army of his own, he's more than prepared for any resistance Mira and her patchy rebel forces can offer, and demands their immediate surrender. Never one to back away from a fight, Mira believes she's ready for anything. But with the battle lines drawn she will be forced to make the ultimate sacrifice. Kill or be killed.
