An epic love story of vampires and poison, innocence and ancient enmities, and the one impossible person who could redeem or destroy them all.
Vampires have started dying, poisoned along the Ortega Highway, so Roman Santos, their warrior leader, joins forces with a maverick scientist to develop a blood substitute. But when the formula turns out not only to sustain vampires, but to humanize them, it leaves Santos and his elite team of fighters vulnerable to inter-vampire power battles, attack by priest-slayers, and to love.
As what began as a rebellious affair with an alluring stranger grows into something deeper, Grace and Roman struggle to keep the secrets of their worlds from destroying their hope for a life together, even as Grace is pursued by priests, slayers, and other vampires, and Roman battles the poison his once-saving formula has become, rebellion within his team, and his own nature. As death closes in from too many sides, can Roman find a way to keep the destruction of his world from the one who might save him?
