Dungeon in great form! I have two main comments on this one. First, the art is great, and the new artist closely matches the feel of the original art. I'd have to check to be sure, but I do feel like the panels are denser in this book, and get a lot of storytelling across on every page. Consequently, this has been one of the most satisfying Dungeon books in a while.
Second, both stories are excellent, but the second one really blew me away. The first sets up some pretty epic-looking battles, advancing the plot of the Twilight series, and then suddenly, right at the end (here comes a spoiler I guess!) Marvin the Red abandons the whole thing and runs off with the Marvin the Dust King to adventure just for fun. And the adventure that follows is great--I don't think I'm exaggerating much when I say it's on par with anything the old Sword & Sorcery greats ever did, a little reminiscient of a Fafhrd & Grey Mouser story (it wouldn't even seem out of place for Howard's Conan), but all wrapped up in Dungeon's characteristic style. Highly recommended!
