I really liked Jim Munroe and Salgood Sam's "post-Rapture" graphic novel Therefore Repent!, which came out at the end of 2007. Imagine its the end of the world, the Book of Revelation was right and all the good folks were zapped up to Heaven ... that's where the story of a couple called Raven and Mummy begins.
Munroe's been working on the sequel, Sword of My Mouth, with artist Shannon Gerard. While Repent! saw angels with machine guns bringing the hammer down in Chicago, this one features Famine of Four Horsemen fame riding into a Detroit where crackhouses are being replaced with farms.
The mini-series from IDW starts in May, and to help people get caught up on the story, Munroe is offering the complete Therefore Repent! online for free. Check out his blog for info on where you can download it. (It's also for sale in his store if you want to actually touch it).
