{completed} ✓ The Doors of Death have been closed, Percy and Annabeth have been saved from Tartarus, but the war is far from over. With the seven demigods preparing for the final and most dangerous battle, everyone is aware that Gaea has the upper hand. With Tartarus on her side, she is gaining more and more power by the second. All the giants are rising, even the ones that have already been defeated. The fight between the Greeks and the Romans is approaching fast. Everything seems hopeless, so why should the seven even try? The only thing stopping Gaea from overthrowing the world is the need for demigod blood, one boy and one girl. The seven are not prepared to give up. They're not prepared to give her the blood of Olympus. Who will be alive to face the final battle? And who will win the most important prize- the fate of the world? “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.”
