Alien Prince Mechanic by Zara Zenia

An outlaw alien mechanic. An abducted female Green Beret. One rescue mission will change both of their futures.

Green Beret Carla Kellogg is used to kicking ass and taking names as one of the only females to ever join the unit, but when she’s abducted by an alien slave trader looking to pay off a debt, she finds herself in the hardest battle she’s ever fought: for her freedom and her life, along with those of the nineteen other innocent human women taken.
Meanwhile, Merrix, mechanic for the renegade Space Knights, and his outlaw vigilant “brothers” learn of the kidnapping of the Earth women while hiding in an asteroid belt in the solar system. Suddenly, what was a stopover for repairs turns into a rescue mission–and a date with destiny for team mechanic Merrix.
Carla has escaped into the bowels of the ship and is determined to do everything she can to free her people from their alien captors. When the rescue mission goes awry and everyone but Merrix is captured, Carla comes to his aid and discovers the Knights’ intent.
But can they trust each other and work together to save the day, or will the time they spend together, crawling around the ship ductwork in close quarters teach them that some itches are too dangerous to scratch?
