La Mariée Mortelle du Sang-Pur

Agent Bailey marries pureblood Count Cassian to assassinate him—but a life-bond forms between them, awakening her "Primal Blood." She discovers her boss Marcus killed her father and imprisoned her mother to use her blood to summon the demon god Cain. Together, Bailey and Cassian fight vampire elders, seize the holy sword, slay a frost dragon on the icy plains, and forge their love. But the demon god rises—war for the world begins.
