The Adventures of the Army of Chaos Trilogy...
Percy Jackson Fanfiction (Books)
Percy Jackson and the rest of the Seven are facing Gaea in one final showdown. Percy defeats Gaea once and for all, but in doing so, risks his own life. As he dies, Annabeth is heartbroken. How will she go on? How will she continue her life with the other half of her soul missing? How will she react when another war starts? Will she ever see her beloved Seaweed Brain again?
It was right after the war against Voldemort and Harry couldn't have been happier. No more deaths. No more being afraid to sleep. No more Voldemort. If he ever knew how wrong he was. He was retaking his seventh year when he finds out about the gods. To say he was shocked would be an understatement. But when he finds out that Voldemort is back with a vengeance, (and a couple of super-powered friends behind him) things go completely out of control. Next thing he knows, a group of Demigods and a mysterious army of cloaked Warriors arrive to save the day.
Must have read Percy Jackson and the Olympians series, the Heroes of Olympus series, and watched the Harry Potter series to understand this story.
