Salvation for the Alien Mercenary by Mina Carter

GAMER. SURVIVOR. HERO?
After escaping her abusive ex, Mira is abducted by alien mercenaries. Now she’s the newest member of the Reapers, on a ship full of misfits and killers where she has exactly zero useful skills. Well, except one: she’s a hell of a gamer.
When she rescues a damaged battle robot, she finds an unexpected ally. But as danger closes in, she must decide if she’s ready to stop running and fight for the man who’s becoming more than just her protector.

AGENT. PROTECTOR. MONSTER?
NOMAD agent Davis Tell’s cover is blown when an enemy attack awakens unknown alien DNA in his blood. As his body transforms into something more than human, there’s just one thing keeps his primal instincts at bay… his obsession with the team’s beautiful newest member.
When the Reaper’s are hunted for the secrets in his changing DNA, Davis must control the beast within or risk becoming the monster Mira fears. But as their attraction ignites and threats mount, they’ll have to face the truth: the alien he’s becoming might be exactly what she needs.
