The Healer by Kelly Lucille

As a powerful Healer in hiding on old Earth, Serenity has managed to avoid the notice of both the Order of Intergalactic Peace and the rebel factions opposing them. That is about to change. Paying off an old debt brings her to the attention of both sides, but it is Lord Mal Ryn of the OIP who stakes his claim.
She thought keeping her heart intact while escaping the most powerful man in the known universe was the challenge.
Turns out they have bigger problems.

This is the beginning of a new series, each book will be a stand alone romance, but the story conflict will be ongoing.
