An ancient volume identifies the missing mirror as an ancient artifact formed by the Aztec god of darkness. A mortal who looks into the mirror will see his or her fate---and can be manipulated by the evil god, who is scheming to regain his power. Taking their destinies into their own hands, the Slayer and her friends rush into a ferocious battle between light and darkness in the shadows of a massive Aztec temple, a battle against perpetual night---and the evil that thrives in the darkness.
