Percy and his friends Annabeth and Grover are sent on a mission to find two new half-bloods at a boarding school in New Hampshire. Something goes wrong, there is a battle, and they are rescued by Artemis and her hunters. But Annabeth is kidnapped and may be in terrible danger, and it’s up to Percy and his friends to save her.
The goddess Artemis is also captured by someone that Percy and his gang don’t know. The half-bloods need to save Artemis and Annabeth, and stop a new villain called The General and their old enemy Luke from getting their evil army stronger.
Back at the camp, the students receive a prophecy that states:
Five shall go west to the goddess in chains,
One shall be lost in the land without rain,
The bane of Olympus shows the trail,
Campers and Hunters combined prevail,
The Titan’s curse must one withstand,
And one shall be perished by a parent’s hand.
The students who are sent on the quest are: Zoe and Bianca (two of Artemis’ best hunters), Grover, and Thalia. Even though Percy isn’t chosen, he tags along anyways. He really wants to save Annabeth.
It was hard to save Annabeth and Artemis, though.
Atlas was the person who captured them both. He made Artemis hold the universe for him, and he threatened that if she didn’t hold it, he would kill Annabeth. He wanted to get revenge on the gods. But Percy and his friends came along and saved them.
Sadly, only 3 people survived on this quest: Grover, Percy, and Thalia. Bianca sacrificed herself for the quest. And Zoe turned out to be Atlas’ daughter, who was killed in the battle against him.
But the quest had succeeded! And all is well until the next book, The Battle of the Labyrinth.
