Brian K. Vaughan, currently publishing Saga, wrote this series of comics - now a series of ten graphic novel volumes - about a man name Yorick. Actually, he's not just a man... he's the man. The only man left alive after something mysteriously killed off every other male primate in the world. Well, besides his companion monkey.
The series follows Yorick as he tries to hide his identity - can you imagine the chaos that would ensue if everyone knew there was one man left alive? - and try to find answers to the mystery of what killed off the men, or at the very least, another male survivor.
