The Astral Mage by Hurri Cosmo

Kyrus is a wanted man. He's an Astral Mage, better known as a "Soul Giver", a race of people who can reattach life force energy back to its source. In other words, he brings the dead back to life. For years the Confederated Authority, the governing body for planets, has been methodically hunting them down and Kyrus is as pure as they've seen. So it becomes a huge risk when Tilbarr, the captain of the Wolf, brings Kyrus on board his ship, and absolutely not because he was falling for the man. But it's not long before Tilbarr realizes he just may have to give up everything in order to save Kyrus… all in all, not a bad trade off.
