I read this book a long time ago but it’s similar to Hidden by T.J. Yelden and The Pack by Kristin Coley.
Specifically, I remember the MC not knowing about the shifter world and being brought into the world because of her mysterious powers and she starts dating one of the Alpha guys. There’s a wolf that refuses to shift back into human form (I think it’s a loner wolf?) either because he’s sick or doesn’t want to and he’s attached to the MC.
