Ragnarok #7 - 12: by Walt Simonson, with Laura Martin on colours and John Workman lettering. Is that not a dream team?
This is the second arc, in Walt's thematic sequel to his acclaimed run on Marvel's Thor (similar to how Peter David's Fallen Angel was a sequel to his criminally underrated Supergirl run). Set in a twilight world, after the death of the Norse gods, the series continues the exploits of a returned Thunder God.
This second arc was a little disappointing, as it spent far too much time wrapping up the story of the dark elf assassin and his daughter, but it had moments of brilliance. The village where Thor was still worshipped by the few remaining humans, even in the face of a zombie apocalypse was a particularly strong moment.
This series is an expensive one. It's $4.99 an issue, and each issue has only 17 or so pages of story. But, if I'm going to pay $5 an issue for anyone, it's going to be for Walt Simonson.
The hardcovers, with a hefty online discount, are likely the best way of following this series. If I can still find a copy of Vol 1 somewhere, I may switch to the trade too.
