A strange fog has rolled into Mahone Bay—and it doesn’t seem to be moving like ordinary fog.

When familiar places begin disappearing behind the mist and unsettling clues appear around Puffeycup Cove, Millie Mollusk knows something is not right. With sharp-eyed Phillip, cheerful Suzie Scallop, and the always-hungry Bulu McGull beside her, Millie sets out to discover what is really hiding inside the fog.

Their investigation leads through confusing clues, unexpected encounters, and more than a few complications caused by Bulu. But solving this mystery will require careful observation, teamwork, and the courage to keep searching when the answer remains hidden from view.

The Fog Moves In On Mahone Bay is the second adventure in the Millie Mollusk Mysteries—a funny and imaginative mystery series inspired by the coastal communities, wildlife, and waters of Nova Scotia.

Perfect for young readers who enjoy mysteries, ocean adventures, memorable characters, gentle humor, and discovering how the natural world works.
