The Heroes of Olympus: The Son of Neptune
A lost hero wakes in a foreign land to fight an ancient war he cannot remember.
The Son of Neptune picks up after The Last Olympian, but the setting shifts: Percy Jackson finds himself alone and on the run from monsters in northern California without his memories, and makes his way to Camp Jupiter, the Roman demigod camp. This isn't just a sequel; it's a cultural collision. Here the son of Poseidon, known to the Romans as Neptune, is an outsider among the Roman demigods. As Percy fights to piece together his past while leading new allies through a landscape teeming with unfamiliar monsters, the narrative sets the stage for the Seven Prophecy—a desperate alliance needed before Gaia's children rise to swallow the world.

Lore & Background
The narrative delves deep into the prophecy of seven, hinting at a grand coalition of demigods required to prevent the awakening of Gaia. It reveals that Percy has been transported across the continent by the goddess Hera (Juno) to serve as a catalyst for this union. The story also tells the history of Hazel Levesque, a daughter of Pluto who died in the 1940s, was resurrected by her half-brother Nico di Angelo and has control over gems and precious metals.
Reader's Guide
The trio's journey is less a quest and more a desperate sprint across a monster-infested continent. Ordered by a prophecy from Mars, they must rescue Thanatos, the god of death, from the giant Alcyoneus, who is hiding deep in Alaska. Along the way Hazel reveals that she was used to raise Alcyoneus in the 1940s but sacrificed herself to stop him, and Frank learns to use the shapeshifting ability inherited from his ancestor Periclymenus. They defeat the giant, and back at Camp Jupiter Percy leads the defence against an army of monsters led by Polybotes, kills the giant with the help of Terminus and is made praetor.
