Beyond Bewitching — Mellanie Szereto

After more than three hundred years as an elder of the Black Triad, Patience Wyndham knows she must risk her life to destroy their leader, the evil snake-shifter Naga. When she travels through time in search of a false candidate to complete the weakened Triad, she is captured by two handsome bounty hunters. She is at their mercy until she discovers she has been Naga's pawn for centuries. Sarah Pennymead may have changed her name to Patience Wyndham, but to horse-shifters Tanner Vale and John Grey, she's still an evil Pennymead witch. Their job is to bring the beautiful witch to justice before the Xanthus clan. Surprised by the faint song that can only come from their yet-to-be-revealed mate, they examine the tattoo on Sarah's back. The markings identify her as the woman who will save their clan from near extinction. But can they trust her with their love?
