Plot Nine months after Percy Jackson 's defense of Mount Olympus in The Last Olympian, Percy finds himself alone and on the run from monsters in southern California without his memories. Under the initial guidance of Lupa, the wolf - goddess and protector of ancient Rome, he makes his way toward Camp Jupiter, the Roman demigod training camp and counterpart to the Greek demigod 's Camp Half - Blood. Upon arriving, he is again attacked by several Gorgons, ( Stheno and Euryale ) and successfully defends a disguised goddess Juno as well as the camp with the help of the guards on duty. Because he protected her during the attack, Juno announces his arrival with her approval, identifying that Percy is a son of Neptune. She further tells him privately that he can only regain his memory by learning to be a hero again and successfully survive the challenges he encounters at camp. Quickly befriending the guards, Frank Zhang, son of Mars ; and Hazel Levesque, daughter of Pluto, and subsequently gets introduced to the praetor of the camp, Reyna, and the augur Octavian, who quickly takes a dislike to Percy. Being outcasts themselves at Camp Jupiter, Frank and Hazel relate to Percy 's outsider status and consider it their duty to help him adjust and acclimate quickly to Camp Jupiter 's routines and leadership. Before any of them have a chance to gain their footing, they are selected to go on a quest to rescue Thanatos, the god of death, from the Giant Alcyoneus who is hiding deep in Alaska after receiving a direct prophecy from Mars, the Roman god of war : Go to Alaska. Find Thanatos and free him. Come back by sundown on June twenty - fourth or die. On their journey, they encounter Phineas, the blind human who helped Jason, leader of the Argonauts on his journey, and befriend a harpy named Ella that supposedly torments him. They also see the three Cyclopes that Jason Grace, Piper McLean, and Leo Valdez encountered in The Lost Hero. During the trip, the trio learns that the goddess Gaea is awakening from several millennia of slumber with a plan to destroy the gods and the world along with them. Her seven Giant children are being woken, each of whom is matched to fight their counterpart god. Each Giant has the skills to oppose one god and they can only be defeated if the gods and the demigods join forces. This proves to be difficult. Percy and his friends manage to defeat the Alaskan Giant and save Camp Jupiter from destruction. During their journey, Hazel and Frank become true heroes who know how to use their powers and have self - confidence. Percy regains his memory on their return to Camp Jupiter and finds an army of monsters ( including Stheno, Euryale, and the three Cyclopes ) led by Polybotes attacking it. Percy successfully defeats him with the help of Terminus, his Cyclops half - brother, Tyson and the hellhound, Mrs. O'Leary. At the end of the book, the Greek airship, Argo II arrives setting up the plot for The Mark of Athena.
