High-school senior Riley Ozment is desperate to change her reality after making a fool of herself on social media. She needs to do something drastic to repair her social standing—like trying out for a Survivor-style reality TV show. Suddenly, Riley's dropped onto a deserted tropical island with nineteen other teens competing for a million dollars and a rumored treasure lost on the island.

But that treasure has a history: a local curse says that seven people need to die before the treasure can be found. And six hunters have already lost their lives in the search. Now the question remains: who will be the seventh?

With a cast of vivid characters who will stop at nothing to win the show, a cursed-island setting, and a priceless treasure waiting to be discovered, The Girl Who Knew Too Much pitches listeners right into a scheming web of lies, love, and betrayal.
