I enjoyed the "Unnatural time" story immensely! Exquisitely written (not just the plot - the personalities were quite superb

).
If I had to choose, I'd really wish for you to turn this into a series of stories (with the same two lead characters). Reminds me a lot of the Donovan and Powell stories by Asimov (except with a supernatural slant). The nuances of the reaper character are nice enough to remind me of Pratchett's Death character. The cherub however, stands without parallel (in my reading at least). A very unique character and I would absolutely love to see more of him

.
The wise-cracking partner thing has been done a lot but in my (albeit inexpert) opinion, this duo was quite the pair

. Please do post an update if you add any more stories.
I reiterate though - this was one
very special short story.
I didn't see the end coming at all
