About the series

The Mia Kingtide series begins when 10-year-old Mia rescues an octopus and receives a magical shell that lets her breathe underwater and speak with sea creatures. In The Octopus' Gift, her connection to the ocean begins. In Guardian of the Coast, 12-year-old Mia uses her growing powers to confront environmental threats along the California coast. In Journey to the Sea of Cortez, she embarks on a two-month expedition. In The Vanishing Sanctuary, 13-year-old Mia faces her biggest challenge as political forces and deep-sea dangers threaten the ocean she's sworn to protect.

The series grows up with its readers, from the magical tidepool story of Book 1 to the eco-thriller of Book 4, which plenty of adults enjoy all on its own.

Real places, real science

Every Mia Kingtide adventure happens in real locations, from the tidepools and kelp forests of Monterey Bay to the islands and reefs of the Sea of Cortez. The research ships are real too, like MBARI's R/V David Packard and Doc Ricketts, and many of the scientists Mia meets are drawn from the people actually working to understand and protect the ocean.
