In the heart of a Renaissance Fair, where history and fantasy exist as one, Callis enchanting voice captivates every listener. Little does she know, her life is about to be transformed forever.

Khuldruk, a formidable orc from a distant realm, arrives with a single mission: to find his one true mate and save the dying magic of his clan. His journey leads him to the fair, where amidst the merry revelry, he hears a song that calls to him on a profound, mystical level. The moment his eyes meet Calli's, he is certain—she is the one he has been destined to find.

But Calli's life is turned upside down when she learns of her true heritage. Growing up she was never truly at home anywhere. But she discovers her grandmother was a siren and she herself possesses untapped magic. Not only that, but she has a mate not from this realm. It's a little much for anyone to handle.

Guided by the whims of a cheeky Scottish witch with a penchant for meddling, Calli will finally find her home in Khuldruk while he finds his mate and a way to save his clans ancient magic.
