Percy Jackson, hero of Olympus, finds himself framed for a crime he didn't commit. Betrayed by both Camp Half-Blood and Camp Jupiter, stripped of his honor and friends, he is cast out into the void of space. There, he is found by Chaos, the Primordial Creator, who offers him a new purpose. Transformed and empowered, Percy rises as Chaos's right-hand commander, "Perseus, the Abyssal Warden." He leads the primordial armies in cosmic wars, wrestling with his past and his new destiny, ultimately becoming the second most powerful entity in existence. His journey is one of loss, vengeance, redemption, and ultimately, a redefinition of power and loyalty.
