So I've been working on this for, I think, a year now and it's finally ready for public consumption:
Here is the link to the CreateSpace eStore and here is the Kindle version and now it's up on Smashwords. And now it's up on Amazon!
It has a whopping sixty-three stories inside, along with twenty illustrations (by me). (Though there are some oblique references, none of the stories feature the Slender Man or the Rake, however, due to their murky copyright.) You get all that, along with an introduction, afterword, and glossary, for $14 (or $6 if you choose the Kindle edition).
Please enjoy and thank you.
Edit: Added the Kindle version, too.
Edit: Added the Amazon link!
