I was really looking forward to seeing Jim Zub on Birds of Prey. DC has decided otherwise though.
Two months before his first issue was to hit the racks, DC moved Jim off of the book and now has Sword & Sorcery's Christy Marx on writing duties. What's odd is that DC has done the same to Robert Venditti on the new Constantine book.
Jim is great writer and big loss on DC's part. I'm sure Jim will get a run with one of the Big 2. Until then, you can check out Jim's work on Skullkickers, Pathfinder and Makeshift Miracle.
