The Son of Neptune

In The Lost Hero, three demigods named Jason, Piper, and Leo made their first visit to Camp Half-Blood, where they inherited a blood-chilling 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...

With an ever-expanding cast of brave-hearted heroes and formidable foes, this second book in The Heroes of Olympus series offers all of the action, pathos, and humor that Rick Riordan fans crave.
