"For centuries they have walked among us--vampires, shape-shifters, the Celtic Sidhe demons, and other magical beings. The battle to reign supreme is constant, but one force holds them in check, a race of powerful warriors known as the Immortals. For Manannán mac Lir, a musician and Celtic demigod, life had become a blur of post-gig parties, expensive whisky, and cheap sex. And then a faerie infant almost dies--a child under his protection. On the hunt for the would-be killer, Mac finds Artemis Black, a stunningly dangerous woman who's inexplicably able to intertwine life magic with death magic. For the safety of his people, he should destroy her. But the aching vulnerability in her eyes calls to him. And the raw desire she inpsires has nothing to do with a spell. Their love may be forbidden, but Mac and Artemis can't go back once they've made...the crossing."--Back cover.
