Charmed By Destiny by Jessamyn Kingley

Richard Marwood has no interest in relationships. After a few awful brushes with intimacy, he refuses to try again. Sex is required for a necromancer to find their soulmate, but Richard doesn’t care. He won’t be disappointed by one more handsome creep.
In the ten years since Lucas Wynnter was summoned from the dead as an inspirit, he has aided his necromancer. Together, they have traveled across the country and stayed in countless rundown motels. But they are out of money. Lucas’s summoner learns that the Marwoods assist abandoned inspirits, and he convinces Lucas to apply for a job.
Although Lucas doesn’t want to be discarded, he does want to help. He shows up at a Marwood casino and, on his first day, meets Richard. Lucas is attracted to Richard, but he works for him. Plus, Lucas won’t be staying. He is building his savings and plans to reunite with his necromancer.
Richard shouldn’t be fascinated by Lucas, but he can’t stop thinking about him. For months they ignore the electricity arcing between them—until Richard’s cousin dares him to take another chance. Should Richard risk humiliation and ask Lucas to spend the night with him?
Lucas is charmed by the awkward invitation, but neither man is prepared for destiny to intervene. Once their souls touch, nothing in their lives will ever be the same.
