BLOOD TREE stars two obsessed NYPD detectives on the hunt for a vicious butcher called the Angel Killer, a sociopath who preys on innocent family members of known murderers in order to "purify" the rest of society. BLOOD TREE confronts the battle of nature versus nurture, how present and future generations are tainted by past generations, and asks who must pay for the sins of the fathers…and perhaps even the sins of the mothers. From PETER J. TOMASI (The Mighty, House of Penance, Batman and Robin, Superman, Black Adam: Dark Age, Super-Sons, Detective Comics) and MAXIM ŠIMIC (Escape from New York, World’s Apart) Collects BLOOD TREE #1-6
