Teen Titans Go Softcover Blackfires Zombie Trouble

When Beast Boy uses Raven's spell book, he conjures a hole in the Multiverse that brings the Zombie Titans to town. If that wasn't bad enough, a terrifying text from Tamaran alerts Starfire that her evil sister is up to no good. It's a diabolical double whammy! Can the Teen Titans battle Blackfire and zombies at the same time? Or will they throw up their hands and become a brain buffet for their undead counterparts?
