Chaos Bleeds seems to be an introduction to the computer game - a door to hell opens, various vampires that may be from the Wishverse and alternate worlds come out, Willow and Tara work a spell to close it, yadda yadda. It's okay, not all that interesting as a story. Sid the Dummy's in it, which is nice - he's in the only long non-crossover BtVS story I've written, Encore, and I have a soft spot for him - but apart from that it isn't memorable.
Reunion is fun. Post Buffy's brief visit to Angel at the beginning of S6 Xander, Anya, and Dawn are speculating about what happened, and telling their own version of events. Trouble is that the stories keep ending up wrong as they're told, with a firey demon attacking Buffy. Anya's version of this is wonderful, since it begins as a demon rabbit... It turns out that Willow has been trying to tell them telepathically that a demon is coming. There's a nasty twist in the tale, of course.
Anyway, for the price it's pretty good value, especially if you haven't seen the comics before. 64 pages, colour, hard cover, and about a third larger than the usual comic size.
While I remember - noticed that Seth Green is in the new version of The Italian Job. Anyone written a crossover yet?
