Moon Fated Mate by Beth D. Carter

Brinnah lives virtually a slave in her traditionalist pack. As an unmated female, she is expected to cook, clean, and follow orders. She thought she’d be in that role forever, until a mating bond strikes … binding her to a mean, self-important sentinel wolf who drags her to the alpha, demanding to be set free.
Brinnah learns that the only person who can break the mating bond is an enchantress, and told to go to Sheridan, Colorado to find her. Only, when she arrives, she meets Everett Brice, and he instantly declares they’re mates.

He’s shocked when she says she already has one.
The more time she spends with Everett, the deeper in love she falls. Could the High Luna have given her a false mate in order for her to find her true moon fated mate?
