Narrowly escaping death at the hands of the Magistrate, Mira travels west, toward the coast. With three weakened human fugitives accompanying her, she searches for the mythical land of Sanctuary. After encountering a pack of wolf shifters, headed by the charismatic—and brazen—Stryker, Mira learns that Sanctuary is real after all. Caldera Grove: home of the Otherkin. Hidden in the mouth of a dormant volcano, it has protected its residents from humans since the early days following the great cataclysm. For Mira—a vampire—Caldera Grove is a land of peace; an escape from the relentless persecution of the humans who once enslaved her, and an end to the daily struggle and bloodshed of being a gladiator. For the humans accompanying her, Caldera Grove means death. Humans, greedy and untrustworthy creatures, are destroyed before they can penetrate its borders. To plead her case for entry into Caldera, Mira must abandon her companions, albeit temporarily, and follow Stryker into the heart of the city. What she finds within Caldera Grove presents her with an unenviable decision between her own desires for freedom and peace, or honor and the human companions who risked it all for her.
