Driven by his need for revenge, Lazarus, the Lore’s most ruthless vampire, plots to seize the throne of Wilyra and rule it along with his betrothed, the fae goddess Maeve who thrives in a borrowed body.

Lazarus has a perfect plan—until he finds Emmalyn, a young mortal who is the daughter of the rebel leader of blood vassals in his kingdom and an integral part of his plan. He captures the young girl to cast her soul out for Maeve.

Emmalyn yearns for a better life to escape from her stepmother and an indifferent father. She never imagined that they would sell her to the royals to save her brother’s life.

But there’s only one problem. Emmalyn tempts Lazarus beyond reason. As the time to cast her soul out draws closer, he must choose between his lust for the throne or his irresistible mortal.

Will Lazarus succumb to lust for power and crown? Or will he risk it all to have a future with her?
