When Grace Cahill dies, her grandchildren, Amy and Dan, and seven other teams take up the challenge she left behind in her will: to search the globe for the 39 clues that will release the hidden power of the Cahills — a family filled with spies, scientists, artists and explorers — and make the winners the “richest, most important people in history.”

Kronos’s army is poised to invade Camp Half-Blood and demon cheerleaders turn up at freshman orientation — Percy has his hands full.

Together with his trusted friends, Percy travels through the United States, battling monsters and hunting the elusive title character.

Percy continues his epic adventures, this time he’s on the high seas and fighting to save Camp Half-Blood from monsters.
