Percy and Annabeth; in Tartarus. Gaea; on the brink of consciousness. Camp Half-Blood; in ruins. What are they gonna do now? After Percy Jackson and Annabeth Chase's fall to the pit of darkness and evil, Nico di Angelo leads the Argo II to the mortal side of the Doors of Death in Epirus, Greece to rescue their two friends and close the Doors. But with the rivalry going on between camps, and Gaea's monstrosity of an army biting at their tails, the mission is futile and the chances of surviving this quest is slim. And the worst part is? Changing their ship's course to help their friends in Long Island. The Roman camp, Camp Jupiter, plans to strike Camp Half-Blood in the name of vengeance...and that scrawny, no-good, teddy bear-killer descendant of Apollo named Octavian. Even though its against their will, the crew of the Argo II knew this was their only chance of ending this rivalry between the two groups, now that they have the Athena Parthenos, the very cause of their fight. And after that, they sailed straight to their demise: The Doors of Death. Can they save Percy and Annabeth and the world? Or will Gaea win this time? Join our fellow demigods to fight to their death in the name of the Gods of Olympus. [Disclaimer: All rights go to Rick Riordan.
