Dark Moon by Kate Douglas

Chanku spirit guide Igmutaka has known since the day he held the newborn daughter of Tala and Mik Fuentes in his hands, that she would grow up to be his. Unfortunately, no one thought to copy Mikaela Star on the message. After years of avoiding her overbearing spirit guide, Star has decided to return to Montana and face the beautiful and irritating man who has haunted her nights for much too long.
But first, she takes a small vacation in California—where Igmutaka just happens to be waiting.
Sunny Daye has known this day was coming. She and Ig have been lovers for years, but both of them accept that they are not meant to be a mated pair. When Igmutaka tells Sunny her man is “out there, and coming closer,” she can barely contain her excitement. But Fen Ahlberg is not at all what Sunny expected–in fact, he is so much more that his mere existence will change the Chanku forever.
Dark forces are gathering, and the four of them—Star, Igmutaka, Sunny, and Fen—will be called upon to alter a fate that could destroy everything they know and love.
