Celtic demigod Manannán mac Lir (Mac) is hot on the trail of Artemis Black, a stunningly dangerous witch who is inexplicably able to intertwine life magic with death magic. Her rare spells nearly killed a faerie infant. For the safety of his people, he should destroy her, but once he runs her to ground, he finds he just can’t do it. Artemis is vulnerable and sly all at once. Every time Mac thinks he’s got her caught, she slips from his grasp. Soon he’s obsessed with her.

Artemis is desperate. So desperate, she’s been skimming life essence from faeries, intending to barter the stolen magic for a demon’s assistance. When her spell gets out of control, she calls it back—but not quickly enough to escape the notice of one very angry, very sexy Celtic demigod.

Passion runs high between Artemis and Mac—but so does suspicion. Who would refuse the help of a demigod? Mac is sure Artemis is hiding something he’s not going to like, and he’s going to stick tight by her side until he uncovers the truth.

Even if she leads him straight into Hell. - series' website
