This is very nearly almost the cover for Outside In Takes A Stab.
The tagline is stated as 138 new perspectives on 138 Buffy stories by 138 writers, but since this cover was unveiled, an extra perspective has joined the others on an extra Buffy story by an extra writer. My contribution has gone from being 1/138th of the whole endeavour to mere 1/139th. I'll live with it. I'll post some more details about the episode that I wrote about soon.
Outside In Takes A Stab is available here.
