Werewolves of the Mountain by Abigail Raines

Millie has her eyes on the prize: taking her blossoming fashion line and turning it into an empire. Life has other plans, however, and a phone call informing her that her father has passed away brings her back to her hometown of St. Neuri.
St. Neuri has changed, with a fog that settles across the town every night, people vanishing and turning up dead, and rumors of wolves hunting in the surrounding woods. Millie doesn’t recognize her hometown anymore – nor the men that reside in it.
A chance encounter leads to her to meet Liam, a dashing bad boy with a smile that shatters her heart neatly in half. She cannot deny the pull she feels for this mysterious stranger. But as the secrets of St. Neuri pull her in deeper, towards legends of werewolves that could very well be real, Millie realizes that not everything is as it seems, including Liam.
