Dark Moon, Shallow Sea by David R Slayton

Raef wants revenge on the knights who killed his goddess, the moon. Her death darkened the night sky, stopped the tides, and left the shades of the dead without a path to the underworld.

Seeking revenge, Raef breaks into the knights’ temple and opens a box, expecting to find gold and jewels among the bones. Instead, he finds a living man, Kinos, sleeping inside.

Raef steals Kinos.

As they run from the knights and grow closer, Raef thinks he’s found a friend, love, and perhaps a secret that may lead to his goddess’s return. If they can’t solve the mystery of Kinos’s imprisonment, the moon will never rise again and the world will drown in ghosts.
