Threat of Darkness — Lauren Dane

Mei is a Warrior for the Balance. She stands between good and evil. So when her boss tells her she's got to head to Tir na nOg to help the Fae she is most displeased. Mei's mother Aine, the queen of the Fae, betrayed and exiled her millennia ago. Or so she's been led to believe. But Aine was misled by her own sister, and suddenly everything Mei has thought was true for thousands of years falls down around her ears as she looks up to see the face of her husband. Her first husband, a man she'd thought was dead. Jayce MacTavish is surprised to find that his wife, thought millennia dead, is alive, but his joy is tempered by the realization that she's got another mate. Mei, Card and Jayce must find a way to be together as three while a threat from the Dark Fae and a new enemy darkens the horizon.
