A promise of revenge.
A murder in sanctuary.
A desperate search for answers.
A storm has taken the island prisoner.
When a ritualistic murder occurs at a muse's sanctuary, Piper Prince must put her own past's mystery on hold to confront this new threat against her and her friends. Could the Sons of Poseidon be seeking new power to fuel their plans for vengeance?
With the aid of two new Protectors, a devoted genie, and the challenging-yet-charming Finnian Kalani, Piper must discover and halt the killer's plans before the ritual's dark magic is unleashed on the island. But what happens when a third task is added to her to-do list—find her missing sister?
Piper Prince will need more than her forensic psychology skills, her friends' help, and her growing power to save her sister and stop a new darkness from rising.
