Apart from Scott Snyder's "Batman" (Court of Owls) and Geoff Johns "Green Lantern" (Sinestro), this is probably my favourite story.
A quick summary for those who aren't familiar with current continuity: Bruce Wayne has a son named Damian, his mother - being Talia Al Ghul, current leader of the League of Assassins - raised and trained him to be a cold-blooded and ruthless assassin. After a series of events, Bruce Wayne got shot back in time and eventually came back. During that time, Damian became Robin and worked alongside Dick Grayson (the first Robin and second Batman). Now that Bruce is back, he has started a new faction of Wayne Industries known as "Batman Inc." where he personally funds Batman and aims to have a Batman for every nation...
...so now we begin. "Batman and Robin - Born to Kill" is simply brilliant. The plot involves a ghost from Bruce's past coming back to terrorise him in the murderous form of "Nobody". "Nobody" also attempts to influence Damian into abandoning his role as Robin and embracing the slaughter. During it all we explore the wonderfully dysfunctional father/son relationship between the two, and from that there are some oddly touching moments.
So there you have it. A new, murderous villain. Exploration of Batman's past. Plenty of father/son moments. Alfred acting as a father to both Bruce and Damian. And lots of action.
All in all, alongside the "Court of Owls" storyline, you should definitely give this a read. I'm sure you'll enjoy it.
