The demigods are safe on a helicopter after Piper uses charmspeak. Her father, Tristan, is deeply disturbed by his encounters with the giants. As she explains the truth about Aphrodite, as well as her own powers, he is upset, saying, “‘I live in a world of monsters’” (474). She considers giving him the memory serum.
Piper persuades the air traffic controllers to let their helicopter land. In an emotional scene, Tristan tells Piper that he sent her away to protect her. She gives him the memory serum, and promises him they’ll talk about her true heritage again when he’s ready. Coach Hedge volunteers to care of Tristan while the demigods complete their quest. Thalia appears in the air and urges them to come quickly; she tells them that “Porphyrion is rising” (480). Leo volunteers to fly the helicopter.
The demigods head to the Wolf House, which Jason now remembers was built by Jack London, an author and demigod. He also realizes he used to live there. While Jason rests, Piper tells Leo that she’s afraid of what might happen when Jason regains his memory. Leo assures her that she can trust him, and trust herself.
Although they are in California, the group encounters an ice storm. They land safely, but a storm spirit destroys the helicopter just as they leap out. They find the Wolf House in ruins, with the Artemis Hunters fighting both the Earthborn and wolves. Leo finds Hera, and she explains that Porphyrion, the King of the Giants, is using her energy to be reborn in the spire across from the one she is trapped in. She urges Leo to free her, and he remembers the prophecy, “the forge and the dove shall break the cave” (495). Khione arrives and turns Thalia to ice.
These chapters set up the major battle of the book.
In giving her father the serum to erase his recent memory, Piper realizes that she has taken on the role of protector. She forgives her father for distancing himself from her, realizing that he always meant best. Secure in his love, she prepares to use her gifts to save her friends.
Meanwhile, Jason’s true backstory becomes clearer. Arriving at the familiar Wolf House, he realizes that he’s been there before, and Thalia shortly reveals that this is where his mother left him. He prepares to do battle with a powerful foe, Porphyrion, the King of the Giants. The lines of the prophecy from chapters earlier return to let Piper, Leo, and Jason see their role in the battle.
In addition, Khione reappears. The Snow goddess’s presence suggests that much of the strange weather the characters have encountered—snowstorms, ice storms—are due to her presence.
