Ghosts of the Sea Moon — A.F. Stewart

In the Outer Islands, gods and magic rule the ocean. Under the command of Captain Rafe Morrow, the crew of the Celestial Jewel ferry souls to the After World and defend the seas from monsters. Rafe has dedicated his life to protecting the lost, but the tides have shifted and times have changed. His sister, the Goddess of the Moon, is on a rampage and her creatures are terrorizing the islands. The survival of the living and dead hinge on the courage and cunning of a beleaguered captain and his motley crew of men and ghosts. What he doesn't know is that her threat is part of a larger game. That an ancient, black-winged malevolence is using them all as pawns... Come set sail with ghosts, gods and sea monsters.
