The Witch’s Rite by Emberly Wyndham

He’s her knight, and she’s his queen.

Aurora Silvermoon is head-over-heels for Alden Stonewood, the village carpenter, but she can’t stop herself from getting flushed when she bumps into Rowan Highcliff, Faunwood’s new knight. With hair of red and eyes of green, he’d stop any woman in her tracks. And lucky for Aurora, when she gets selected as the May Queen of the Beltane festival, a certain red-haired knight gets picked as her Horned God.
All it took was one chance meeting with a witch in a mercantile, and Rowan is already falling hard. While chasing her around the Beltane bonfire in a ritualistic celebration of summer, something ignites inside him, and he knows he wants her for his own. Until she reveals that she’s already got a lover.
But she claims she wants them both, if only he’s willing. Rowan isn’t sure about it at first—he’s never been with a woman who already has a man—but if that’s what it takes to hold on to his witch, then so be it.
What neither of them knows is that the fertility goddess has a few tricks up her sleeve, and she’s about to make this topsy-turvy dynamic a lot more complicated.
