Behemoth by Kenzie Kelly

Gaelynn believed escaping a cult would be the hardest thing she’d ever do, but protecting her heart is an even more daunting challenge.

She escaped Guiding Light Mission in the dead of night, fleeing from the leader who called her “special” and his fanatical minions. She vowed never to live under anyone’s rule again. She sought refuge in Damruck, where she built a life with friends and a fulfilling job. She thought her days of running to stay one step ahead of the cult leader were over.
Then they found her.
She’s safe under Behemoth’s protection, but how long can she stay, knowing she’s putting him and everyone he loves in danger?
Vital “Behemoth” Benoit is a crack-shot assassin accustomed to working alone.
He left the military behind after a mission that nearly cost him everything. He has a job he loves and he’s found his fated mate. Life should be easy, but his mate is being stalked. He’ll stop at nothing to keep her safe—but can he convince her to stay forever?
