Maklr by Holly Hanzo

Maklr has dedicated his life to helping the injured. When the human females began to arrive on Klaga from slavery situations on various planets, he requested a more permanent position. He was sent to Klaga to be the head medic at the transitional living center for the humans. Though he has a team of Klagan doctors at his beck and call, he still prefers a hands-on approach to heal both the bodies and minds of the rescued humans.
Nell is one of the first rescued humans to arrive in the transitional living center on Klaga. She needs time to heal and process her trauma. She’s withdrawn into her mind, shying away from any attention. Around Maklr, she feels almost comfortable, and is inexplicably drawn to him. Are her feelings just a form of Stockholm Syndrome, or could it be something much more? Could he possibly be her salvation?
Can a Klagan Medic Warrior resist the urge to keena bond his fated one to him while she’s so traumatized? Can a withdrawn woman learn to trust her instincts and have faith in herself once more?

This is Book 4 in the Klagan Warriors series, but it can be read as a stand alone, though it does feature characters from prior novels. It has a HEA, no cheating and no cliffhangers.
