Vendetta by Emmy Chandler

Having escaped the lab where they were altered with alien DNA, Vaughn Coleman and his fellow super-soldiers answer an ad for a ship capable of getting them far from the prison planet they’ve just fled. Meshach Larsen, autocrat of a notorious isolationist planet, is willing to accept payment in services rendered, rather than credits.

The job? Find and return a mysterious crate that was stolen during shipping. But their mission is complicated minutes after accepting the job when Vaughn finds a beautiful, sheltered stowaway on their already crowded short-range shuttle. Grace can’t remember how she got from the secluded convent where she was raised to the planet Gebose, where women aren’t to be seen or heard. Where she will soon be forced into service as a concubine. All she knows for sure is that the shuttle leaving to run an errand for Meshach offers her best chance at escape.

But Grace has no way of knowing that the man who discovers her onboard isn’t exactly human. That alien urges and instincts Vaughn can’t quite control—collectively known as his beast—are insisting she is his mate. That he must claim, love, and defend her at any cost. Even if protecting her from Meshach means sacrificing the crew’s best chance to settle their vendetta with the ruthless corporation that turned them into monsters.
