An anicent volume identifies the missing mirror as a magical object 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, who is scheming to regain his power. Taking their destinies in 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 dark hours.
