So far there are 4 trades, and the series in about to go into issue 32 I think. It's a great book, one of the few from my library that I've sent out purely to get other people to read.
Here's the pitch E, A plague sweeps over the earth, killing every single being with the Y chromasome except for Yorrick Brown and Ampersand, the helper monkey he was training. So far the series has been about searching out the causes of the plague, and hopefuly some way for humand kind to survive, and Yorricks personal search for purpose in the world, hopefuly as more than a breeder. The monthly just revealed how Yorrick survived the plague, and is about to leave america, hopefuly for Australia, where Yorricks Girlfriend was when everything went to pot.
Pick it up man., it's a marvel.
