The Souls of Witches. Legends of the Pale, #4

Orphaned at the age of six, Lars's earliest memories are of the violent encounters between the demon who sired him and his demigod mother. His unique history, which he'd like to forget, is what allows Lars to live a charmed life within the supernatural communities collectively known as the Pale. With the goddess Rhiannon as his patron, he wants for nothing. But after encountering Rowan Morgan at a local Witches Ball, Lars must face disturbing truths about his banished past before his ignorance and cravings kill her.      Rowan is a solitary witch by nature and a kitchen witch by inclination.
The life she has carved out for herself is a small one, but also deeply satisfying. Rowan loves nothing more than tending her herb garden, baking sweets for the local café, and spending time with her best friends. She is fiercely independent and has never truly felt as if she were someone's other half. Yet after a single night in the arms of a dark and mysterious lover, Rowan is forced to reconsider her past assumptions about the existence of soulmates.
And if she and Lars are truly destined for one another, then how can such drastically different people learn to share a life together?
