The Tor freebie, Four and Twenty, was spooky in a non-threatening sort of way. Gave me little goosebumps, but I wasn't afraid to walk thru my house with the light off afterward. Plus, it's set in some interesting locations that I've enjoyed: Chattannooga, Macon GA, and the Florida Everglades.
Yes, I know I misspelled Chatin... Chattan... That Tennessee town near Atlanta. And I'll misspell it again next time also. I love the town despite its having an impossible spelling.
