The sold-out, smash-hit 6-issue miniseries co-published with IDW is now available in paperback! It all starts in Gotham City, as a series of deadly raids leads Batman to believe he is up against a group of highly trained ninjas. Somehow, the Foot Clan has crossed over to another dimension-but they haven't come alone: Leonardo, Raphael, Donatello and Michelangelo are on their trail!
