After receiving a call from Grover the satyr in Westover Hall, Percy, Thalia, and Annabeth speed to the military school to recruit the two Half-Bloods that Grover found. But they weren’t alone. The manticore was lying in wait, preparing to steal away Bianca and Nico de Angelo, demigods whose parentage was unknown. In an attempt to keep the two demigods from being taken, along with her other friends, Annabeth leapt onto the back of Dr. Thorn, the monster that was sent by a more powerful force. When Artemis and her Hunters arrived, the manticore plunged over the edge of a cliff, taking Annabeth with him.
She wasn’t the only one lost. Only days later, Artemis went missing. A council was held at Camp Half-Blood to determine who would go on the quest to save Artemis and Annabeth and find the monster that the goddess was searching force, the beast that could be the ultimate downfall of Olympus.
Percy, Grover, Thalia, Bianca, and Zoë Nightshade, the Lieutenant of the Hunters, were sent on the quest. They left the camp on a mission, but they knew there would be dangers ahead of them; the prophecy voiced by the Oracle foretold it.
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 perish by a parent’s hand.
Along the way, Percy rescued a cow serpent that had been trapped beneath a teetering sunken ship. Immediately the creature was fond of the boy, happy that he had rescued him. Unable to recognize it, Percy named it “Bessie.”
In the Smithsonian, the group was attacked by seemingly invincible skeletal soldiers that had been created by their terrible foe, The General. These “men” pursued them across the country, causing problems everywhere they turned. It wasn’t until Cloudcroft, New Mexico that Bianca managed to kill one of the skeletons with her dagger.
But her heroism wasn’t long-lived. Shortly thereafter, in the junkyard of the gods in the desert, Bianca de Angelo was lost to one of the dysfunctional creations of Hephaestus.
With grief in their hearts, they continued on until they came to the mountain that held Annabeth and Artemis captive. They were unaware of the evil that was awaiting their arrival. The General had them trapped, and, in a horrendous battle, they overcame the Titan. Atlas, the Titan that was the mastermind behind Kronos’s plans and The General, was forced under his old punishment of holding the sky on his shoulders.
Zoë didn’t survive the fight, as she was struck down by Atlas, her father.
The remaining quest members quickly flew to Olympus where the gods were deciding the outcome of Bessie, the monster that the goddess of the moon had sought for. However, due to Percy’s fast mind, the Ophiotaurus was saved and the Half-Bloods were rewarded for their bravery.
