Here's the solicitation copy for the latest entry in the Black Hammer saga: "Picking up immediately where we left off -- Lucy Weber has become the new Black Hammer and right as she's about to reveal to our heroes how they got stuck on the farm and can escape she vanishes. Now our new Black Hammer finds herself trapped in a gritty world filled with punk rock detectives, emo gods, anthropomorphic humans, absurdist heroes, and many more weirdoes, in a mad world in which there is no escape!"
