Soulbound by Charlotte Blair

Fate can be an unkind mistress.

A demon on the rise and a woman in a slump. A drunk hookup ruined by a demonic attack. Two souls, permanently linked.

Alyssa has enough on her plate. With a bad breakup and trouble involving one of her kindergarten students, she doesn’t want to deal with a handsome stranger who might be more than human. As she investigates, she realizes that she’s in way over her head. But by then, there’s no way out.
Samiel is used to being in control. He’s on track to take his father’s throne, and nothing stands in his way. Nothing except a human by the name of Alyssa. The connection between them is powerful, but she is already ruining everything he has worked for. He has to own her before she destroys his life.
After meeting, their lives are forever intertwined. And disaster lurks around every corner.
