In The Lost Hero, three demigods named Jason, Piper, and Leo made their first visit to Camp Half-Blood, where they inherited a quest: Seven half-bloods shall answer the call, To storm or fire the world must fall. An oath to keep with a final breath, And foes bear arms to the Doors of Death. Who are the other four mentioned in the prophesy? The answer may lie in another camp miles away, where a new camper has shown up and appears to be the son of Neptune, god of the sea. . . .
