Well, this is just all kinds of awesome. Hyperion has posted the book cover, release date, and plot summary for the first book in Rick Riordan's "Heroes of Olympus" series. Behold The Lost Hero, coming out on October 12th:
"After saving Olympus from the evil Titan lord, Kronos, Percy and friends have rebuilt their beloved Camp Half-Blood, where the next generation of demigods must now prepare for a chilling prophecy of their own:
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.
Now, in a brand-new series from blockbuster best-selling author Rick Riordan, fans return to the world of Camp Half-Blood. Here, a new group of heroes will inherit a quest. But to survive the journey, they'll need the help of some familiar demigods."
