East of West, Vol. 1: The Promise

I was really luck to score all ten volumes for only $50 on Kijiji, and it's been the best blind purchase I think I'll ever make. I would say that it requires reading the Wikipedia page to download what I think is required context before diving in, otherwise you'd truly have no idea what's going on for the first few issues. I was completely hooked after the first issue. Who wouldn't love an alternate History Sci-Fi/Western featuring the Four Horsemen of the Apocalypse?
