Her Human Bodyguard by Lea Linnett

She hired a cleaner. What she got was something entirely different.

Devis Sidana is no good at being a levekk. She’s messy, lazy, wild. No male has ever wanted her for more than a night. Hiring a delicate, weak human to tend to her home was supposed to help her get her life in order.
But Scott turns her life upside down, and he is far from delicate.
He’s huge and scarred and terrifying. His glittering gaze lights a fire in her cold blood unlike any she’s ever felt. He makes her feel seen in a way her own kind never did.
And he has pledged himself to her, on a planet where their coupling could threaten his life.

Trapped beneath the dome of New Chicago, Devis can feel the threat of discovery pressing in around them. Scott says he’ll keep her safe, but Devis has a greater fear.
How will she protect her bodyguard, should the worst happen?
