Percy and Annabeth are back from Tartarus, but nothing could've prepared them for the worst. The Seven are united once more, as Nico di Angelo, Coach Hedge and Reyna Avila Ramirez-Arellano journeys across Europe to Camp Half-Blood and return the Athena Parthenos, which will hopefully remove the rivalry of the two camps. The crew of the Argo II sails the vast Ionian sea, across the Saronic Gulf Islands and lands at Athens, Greece wherein a large army of Gaea, a mix of monsters, giants and traitors, awaits them until Mother Earth, with the help of the blood of two demigods, opens her eyes at the Feast of Spes and crush every living thing in existence and spread chaos. The demigods fight with all their might, swords colliding with enemy swords, hero blood dripping together with evil blood, armies falling and retreating, and Hope...fading away into bits and pieces until every last bit of it vaporizes into extinction. Many things are need to be done in less than two weeks, but Leo's desire to find Calypso and get her out of exile grows stronger by the minute. Nico, Reyna and Hedge clings onto what seemed like the last thread of faith--to bring the two camps together and fight against Gaea. Their fates are at death's door. It's time to defeat the impossible. {DISCLAIMER ALERT: All rights go to Rick Riordan. This is not the actual Blood of Olympus and this is just a mere fan-fiction.}

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.
