When seventeen-year-old Georgia’s brother drowns while surfing halfway around the world, Georgia refuses to believe Lucky’s death was just bad luck. Lucky wouldn’t have surfed in waters more dangerous than he could handle. Then a stranger named Fin arrives in False Bay, claiming to have been Lucky’s best friend. Soon Fin is working for Lucky’s father, charming Lucky’s mother, dating his girlfriend. Georgia begins to wonder: did Fin murder Lucky in order to take over his whole life?  

Determined to clear the fog from her mind in order to uncover the truth about Lucky’s death, Georgia secretly stops taking the medication that keeps away the voices in her head. Georgia is certain she’s getting closer to the truth about Fin, but as she does, her mental state becomes more and more precarious, and no one seems to trust what she’s saying.

Is Georgia’s descent into madness causing her to see things that don’t exist--or to see a deadly truth that no one else can?
