In Percy’s fifth and final adventure a prophecy suggests that, when he reaches sixteen, the fate of the whole world will rest in his hands. This son of Poseidon and American teenager must battle Kronos, the King of the Titans, before he destroys the world, starting with New York.
Percy must make a dangerous trip to Hades and win over the Gods to do his bidding. He has the help of most of his demigod friends, but one of them is a traitor, revealing his plans to the enemy.
The two girls in his life are both behaving strangely. Is either of them romantically interested in Percy?
Witty, touching, sad and gripping by turn; this is a satisfying finale to an exciting series.
