The House Of Hades

The seven half-bloods were sent on a quest to stop Gaea. But along the way, they discover that Nico Di Angelo has been captured. They saved him, but that came with a price, as Percy Jackson and Annabeth Chase fell into Tartarus. Now the five demi-gods, along with Nico, are traveling to the House of Hades, to hopefully close the Doors of Death on the mortal side. Will they succeed? Or will they fail, and doom everyone's fates?
