The Inescapable Hound by Victoria Pauley

He’s her pet. She’s his mate.

While attending a winter party with her friends, the last thing Cara expects is to end the night wet, muddy, and bringing home the ferocious dog who saved her.
What she doesn’t know is the animal she invited into her apartment isn’t a dog at all.
Lucian, a hellhound who escaped his old life and just wants to teach Mythology in peace, has no intention of playing pet, least of all to a woman with traces of a bloodline he’s been taught to hate. But when she offers to bring him home with her, he finds himself following along like a dutiful pup.
He doesn’t understand why until his hound reveals the truth.
Cara is his mate.
When she shows up in his class a few days later, Lucian realizes that despite how hard he might try, there’s no escaping his fate.

The Shifterverse is an interconnected series of standalones.
