Batman by Grant Morrison Vol. 2 (Omnibus)
The Dark Knight has fallen, sacrificing himself in the Final Crisis. Tim Drake has laid down the mantle of Robin to search the world for a sign that his mentor can be brought back from oblivion. Now Dick Grayson has taken up the cape and cowl of his former partner, and Damian Wayne has become a deadly new Robin. Together, they must overcome a pair of rival vigilantes with ties to their own tragic pasts-and stay away from each other's throats long enough to succeed.
