Deputy Bear by Scarlett Grove

Holiday blues …
When her boyfriend betrays her, Harper Brown leaves his cheating ways behind and starts a new life on Fate Mountain. Living in her grandfather’s rustic hunting cabin and working as a bank teller is a lot better than being miserable. Until her new boss turns up dead — and the man investigating her is the same one she’s been matched with by a human-shifter dating site.

Criminal claims …
Knox Carter can’t believe the beautiful woman who’s stolen his heart is not only his fated mate, but a murder suspect. Instead of courting her and building their life together, he’s under orders not to see her while he tries to prove she didn’t kill anyone.
Christmas surprise
Can Knox find the real culprits in time? And can Harper find a way to tell him the secret that will make them an instant family?
