All-Star Batman, Vol. 1

"Batman finds himself trying to help old friend Harvey Dent ... now known as the villainous Two-Face. The Dark Knight accompanies his foe on a cross-country trip to fix his scarred face and hopefully end the Two-Face identity forever. But when the former Gotham City D.A. sets a plan into motion to free himself, the road gets bumpy and every assassin, bounty hunter and ordinary citizen with something to hide comes out in force with one goal: kill Batman! Handcuffed together on the road to Bat-hell, this is Batman and Two-Face as you've never seen them before!"--
