Not of This World by Tracy St. John

He was her savior, but she was his salvation. Jeannie Gardner escapes from her captors’ clutches only to find herself trapped on a planet far from Earth. When she is discovered by a muscle-bound warrior, she must prove to him, and the Council of Elders, that she is not a creature set free from a lab, but a sentient being from another planet.

If she succeeds, they will send her home. If she fails, she will be executed. Risnar warrior Kren Bolep is duty bound to protect his village from the Monsuda and their creations. But this small pink-skinned female is different, special. As the bond between them grows, Jeannie’s vulnerability invokes Kren’s protective instincts, and he vows to uncover the truth and secure her future.

But there is a bigger threat looming. The Monsuda are coming to get Jeannie, and they’ll use whatever means necessary. When Jeannie is taken, Kren is forced to choose—disobey the Elders and place his people in danger, or lose the only person who makes him feel whole.
