The year is 2512. The oceans have risen. A new dawn of piracy has begun.
Following the sudden death of their father, teenage twins Grace and Connor Tempest hastily depart the suffocating small town of Crescent Moon Bay in their dad's old sailing boat. Caught in a vicious storm, they are shipwrecked and separated in the cold, cruel ocean.
Connor is saved by Cheng Li, Deputy Captain of The Diablo - the notorious pirate ship, captained by flamboyant rule-breaker and pirate royalty, Molucco Wrathe.
Grace, meanwhile, is taken by handsome Midshipman Lorcan Furey, onto a mysterious ship with no name, a blood-red deck and an enigmatic, seemingly absent, Captain.
In a world of danger and secrets, will the twins ever be reunited?
