Batman Vol. 5: The Rules of Engagement — Tom King

In this new collection, the Penguin waddles into a turf war-and Batman is there to stop the violence. But the Penguin is on Batman's side for once, and the crime boss sees dangeron the horizon. How can he convince the Caped Crusader he's on the level? Plus, appearances by Professor Pyg, John Constantine, and the boy who wanted to be Bruce Wayne-in the worst way possible! And then, someone is forcing Batman to relive some of his darkest, most traumatizing fears. Collects Batman #58-69.
