Commander’s Mate by Clarissa Lake

While they were fighting the Consortium’s war against the Sargus Empire far from their home world, the Sargus Empire attacked Farseek, leaving mass destruction in its wake. Only about a dozen survivors remained the tell what happened—a dozen of over a million. Those who weren’t killed were taken to become slaves of the Empire. As the story opens, Commander General Zared Maktu has found the piles of wreckage that is all that’s left of his family’s neighborhood.
Nothing the Consortium has to offer can compensate what was lost. Time for the company of Farseek Dreadnought One to make a new plan. They must find those who were taken alive and bring them home. After terminating their contract with the Consortium, they take a job to rescue a governor’s daughter stolen to be sold into slavery.
Commander Maktu doesn’t just rescue the Governor’s daughter and her companion. He and his company take all of the 100 abductees from the auction house. Only two are from Farseek, but there are four unusual females from a planet called Earth—and one of them is his fated mate Harper Avery. Things heat up from there.
