Mike Barr's follow-up to Batman: Son of the Demon. With Batman and Al Ghul once against adversaries, Ra's realizes that he is in need of a new heir. With no human on earth outside of Bruce Wayne worthy of being the Demon's Head, Ra's procures himself a wife (an aging Hollywood starlet), determined to have a son.
And when an environmental scientist is abducted, Batman is forced to confront his greatest foe once more. Ra's has a new dastardly plan, to repair the damage to the ozone at the cost of almost all human life on Earth.
