Magic's Promise: A Nocturne Falls Universe story

Runaway bride Katya Dostoyevna escaped to Nocturne Falls ten years ago. She's lived a quiet life since then, establishing a much-needed animal sanctuary. It's good work for a shy witch who prefers to talk to animals, both supernatural and mundane.
Scorned groom Danil Leonov has finally tracked down the girl who fled from their arranged marriage. He doesn't want to marry her any more now than he did then, but she left with something he desperately needs. The fate of the fae world depends on it.
But he's not the only one after the microchip he developed. And after he and Katya connect, Danil starts to wonder if it's the tech he really wants, or the woman he didn't realize he loved.
