The Vestal’s Steward by Alix Nichols

War is coming. Insurrection brews. But royal prioress Aynu Eckme keeps out of politics. To her, only the temple counts.
Aynu is relieved with her recent hire of Rhori Tidryn, a former prizefighter. He’s humble, competent, tough. Just the man to ensure her safety in such troubled times!
It matters not that he stirs something peculiar in her. Something improper and beautiful…
An insurgent by night, Rhori loves his new job as Prioress Eckme’s steward. Even the worst part—drinking a foul goo every week to suppress his baser needs.
Rhori would do anything for the prioress.
When he takes the vow of devotion, he’s prepared to serve her for the rest of his life. He’d die for her without blinking an eyelid. It would be easy, given how much he worships her already.
The problem is, he worships her in all the wrong ways.
