An execution-style murder sends a message.

Old cases haunt Maui's detectives.

An external force threatens Pele's island home.

Now partners, Maui PD Detective Sergeants Keone Boyd and Angela Beyers investigate the brutal murder of a local drug pusher. The body is found across the street from Maui PD headquarters, with its tongue cut out and its lips sewn together. For Keone and Angela, the murder stirs echoes of their former cases.

In the midst of the investigation, Keone is summoned by his elderly grandmother. In her visions, Pele, the most powerful of the Hawaiian gods, wakes from her slumber to confront an ancient evil that threatens their beautiful island home—an evil Keone has faced before, thousands of miles away, and failed to destroy. Can this be related to the murder? What are the visions trying to tell him?

This time Keone has no choice. Either he ends this evil, or the evil ends him—and everyone he loves. This lovely and vital island continuously reminds Keone that their souls are inextricably linked to the source of their very existence in the bubbling fires of Pele.
