Mia Kingtide

Book Four in the Mia Kingtide Series

When the protected waters of Monterey Bay come under threat, thirteen-year-old Mia Kingtide finds herself caught in a rising tide of political power, corporate greed, and oceanic mystery.

With her magical shell, Mia can speak to marine creatures, breathe underwater, and sense the pulse of the sea. But when she learns that government protections for the sanctuary are being stripped away, and a tech billionaire plans to exploit the ocean's resources, she realizes this fight is bigger than she ever imagined.

As strange vibrations echo from the deep, sea lions vanish, and a mysterious machine hums in the depths of the Monterey Trench, Mia is pulled into a secret that could change everything. With her dad, her animal allies, and the ocean itself by her side, Mia must decide how far she's willing to go to defend the place she loves most.

Perfect for fans of environmental adventures, ocean magic, and brave young heroes, The Vanishing Sanctuary continues Mia Kingtide's journey with new depths of danger, discovery, and determination.
