After reading all this stuff about and diggory, I started thinking maybe I could do some revisions and put together some of my homeless short stories in a book. However when I added up the word count, the 4 stories I had in mind came to just over 10,000 words althogether. These stories are all ghost stories. I do have other short stories that aren't ghost stories that I could add if 10,000 words is too short to bother with, but that means there won't really be a theme.

Is a 10,000 word book silly? Should I just pick the stories I particularly like no matter what the theme and have a longer book?
