The Lost Hero
Three demigods named Jason, Piper, and Leo make their first visit to Camp Half-Blood, where they inherit 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.
The Son of Neptune
In a Roman demigod camp, thousands of miles from Camp Half-Blood, a new camper shows up and appears to be the son of Neptune, god of the sea . . .
