About the series

The Mia Kingtide series begins when 10-year-old Mia, growing up in the small coastal town of Sand City, rescues a stranded 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 with a trip to the Monterey Bay Aquarium and the real scientists who inspired her journey. In Guardian of the Coast, 12-year-old Mia confronts illegal fishing and environmental threats from Año Nuevo to Half Moon Bay. In Journey to the Sea of Cortez, she sails two months aboard the family trawler Pegasus, retracing the route made famous by John Steinbeck and Ed Ricketts. In The Vanishing Sanctuary, 13-year-old Mia races to stop a deep-sea mining operation off Pacific Grove before Monterey Bay's marine sanctuary is lost for good.
