Ten years after the defeat of Gaea, a new threat emerges. Percy Jackson, the Hero of Olympus, has taken up the mantle of Camp Director at Camp Half-Blood. One of his duties is finding and escorting new demigods to camp. Dante Walker, the son of Hecate, wishes for a better life. His father was abusive, and his step-mom cares more for gambling and drugs than him. When he meets Percy Jackson, his world gets turned upside down.
