At the age of five, good witch, Beatrice Manchester, comes into her powers. Her doting, magical Grandpa reads her bedtime stories from the Book of Cauldrons, Spells, and Legends. He tells the tale of the Chromium Cauldron. While wintering in Palm Beach, Florida with her family in 1912, she meets a young merman, Prince Peter of Atlantis. Just like the story from the Book of Cauldrons, Peter presents Bea with a Chromium Cauldron. With the proper spell and potion, the cauldron allows her to breathe underwater. The sea nymphs prophesize that Bea and Peter will wed on her 16th birthday. They also predict that Poseidon, angered with the humans, plans to sink the Titanic. A heart wrenching memory loss and an overprotective King of the mermaids, keeps Bea and Peter apart.

Ten years later, in the roaring 20s, Bea's parents take her to the Biltmore Estate to mingle with the heirs of America's wealthiest tycoons—Carnegie, Astor, Flagler, Morgan, and Vanderbilt. The spellbinding, beautiful heiress is smothered by sought after suiters. But something prickles her memory, and she knows her parents are hiding something important—something significant that's supposed to happen soon. Just before her 16th birthday, Bea's memory is completely restored. But the Gods are angry at the humans again and plan to create the largest and strongest hurricane ever formed to annihilate the islands and the entire state of Florida, and Atlantis is directly in it's path.

From the Breakers to the Biltmore to Atlantis, Bea encounters countless magical creatures—sea nymphs, mermaids, Gods, and angels. With the powerful Manchester coven, they fight the massive Hurricane. Will the Manchesters defeat Mother Nature, forced by the Gods? Will Bea and Peter, true loves, be reunited at last and fulfill the prophecy?
