Fire in the Ocean

A former PR exec is out to save the world from evil in this paranormal fantasy steeped in Ancient Hawaiian lore by the author of The Obsidian Mirror.
After saving the world once, Sierra Carter has earned a little sun, surf, and sand in Hawaii. With her boyfriend away on business, she’ll make do with the company of her friends Chaco, also known as Coyotl the trickster, and Fred, a mischievous mannegishi with the power to disappear at will. But when the motley crew is swept overboard during a whale watching trip, they are plunged into a new adventure that will test their magical mettle—and suddenly Hawaii is anything but a day at the beach.
Pulled ashore on the island of Molokai, Sierra finds hospitality and powerful friends. When she is asked to prevent the construction of a potentially disruptive energy plant, she is drawn into a tangle of supernatural proportions. But the machinations of the ancient gods can be opaque at best—and sometimes downright lethal for mortals.
