The Queen of the Ocean has risen.
Once more, the Crown has been claimed by a tainted soul.
 
As a new curse comes to life, Leilani feels the sea slip into shadows darker than ever before, and realizes it is up to her to defend it.
 
But how can she fight back against the most powerful queen all of mankind has ever known?
How can she fight back, when her Guardian, her dear stranger from the sea—the one who has been chosen to protect her, the one man she has given her heart to—is wearing a mask she cannot see behind?
 
Leilani is taken to the sinister world of the Deep, where there are countless secrets to be unraveled, violent games are being played, and where she will have to choose whether she will remain the girl she has always been... or embrace the side of herself that she's been running from for years.
 
Maybe only then, she can save Keanu.
Perhaps only then, she can save the sea.
