Ever since a hurricane devastated the small town of Mercy, Louisiana, a red algae bloom has taken over. Mutated wildlife lurks in the water that rises by the day, but Mercy has always been a place where monsters walk in plain sight. Especially at its heart: the Cove, where Noon''s life was upended long before the storm at a party her older boyfriend insisted on.

Now, Noon is stuck navigating the submerged town with her mom, who believes their family have been reincarnated as sea creatures. Alone with the pain of what happened that night at the cove, Noon buries the truth: she is not the right shape.

When Mercy''s predatory leader demands Noon and her mum capture the creature drowning residents, she reluctantly finds an ally in his deadly hunter of a daughter and friends old and new. As the next storm approaches, Noon must confront the past and decide if it''s time to answer the monster itching at her skin.
