Gotham City is plagued with crime and corruption in places high and low, but one man has taken a stand against evil in all its forms: the dark avenger known as Batman. Now, the unbelievable has happened: Ra's Al Ghul, the ageless 'Demon's Head' and one of Batman's most dangerous foes, seems to have returned after meeting his death at the hands of his long-lost daughter Nyssa. But why is he after Batman's teenaged son, Damian, the offspring of his other daughter Talia? What offer will tempt Robin to help Ra's? And can the Dark Knight save both his adopted and biological sons? Written and drawn by a host of stars including Grant Morrison ("The Invisibles"), Paul Dini ("Countdown") and many more, this is a Bat-story that cannot be missed!
