Found By Frost by Terry Bolryder

Boreas Everfrost, now known as “Brett” in the human world, has finally found his soul bond. The only problem? She has no clue he’s a powerful fae ice prince from another world. Nor does she know that she’s really a fae princess, with gifts and strength far beyond what she comprehends. Which is why Brett will stop at nothing to protect the independent, secretive woman upstairs from the forces of chaos that seek to capture her before her true power awakens.
Avery Williams doesn’t know why she was born with incredible physical strength. But that won’t stop her from using it to protect those who can’t protect themselves in an ever-worsening world. But when four beautiful, mysterious men move into the apartment downstairs, Avery starts to feel something for one of them that she’s never felt before. Attraction. Desire. Need. Too bad it’s the stubborn one with ice-blue eyes that seems obsessed with her from the start.
Even though Brett comes across as proud or imperious, Avery quickly finds out that he’s the kind of man that would defend her to his last breath and do the dishes without asking. And for all of his bravado, he’s sweet and deeply empathetic. But a powerful figure is watching from the shadows, getting closer with every breath, and even a powerful ice prince might not be able to stop him.
