For years, the whispers and legends of a lost city hiding in the Pacific Ocean were just that; legend. On the day Kaimi discovers his parents, the Queen and King of Mu, murdered, Mu's most powerful weapon fired, sending a pulse rushing towards the North American west coast.

After the 2025 Great Pacific Pulse Event, or Pulse, vomited up much of humankind's trash in the Pacific Ocean along the North American west coast. The mysterious occurrence causing the largest environmental disaster in human history, people are no longer certain there is nothing concealed in the depths of the ocean.

Scientist Karen Linn and billionaire investor Michael Donovan want to find out what actually happened that day five years ago. Will Michael's life in the adult entertainment industry and Karen's moniker in pseudoscience keep them as social pariahs, or are they on the cusp of finding a civilization that has been kept out of our grasp, deep in the world's largest ocean? How does the event from five years ago tie into the murder of the Queen and King of Mu? What lies under the sea may be bigger than anyone can imagine, and neither civilization may be ready for the truth.
