Bound by a dark contract, Zaria must submit to Lucien’s needs—physical, emotional and otherwise—while he fends off rogue immortals and prepares to lead an ancient vampire syndicate on the brink of civil war. But as their fates intertwine, Zaria realizes her blood may be the key to a power long thought extinct and that the price of survival may be her soul.
