The Son of Neptune

The Son of Neptune is the second book in the Heroes of Olympus series, and is set to be released in Fall 2011, and is able to be seen on page 557 of the First American Edition Hardback copy of The Lost Hero.

It is likely that the title, The Son of Neptune, is referring to Percy, who is probably at the Roman camp for demigods, most likely, like Jason, unaware of who he is.

It will possibly have Leo's airship he created at the end, also.

It might be a story like the Lost Hero but from Percy's point of view. As he was swapped with Jason and is at a Roman Camp Half-Blood.
