So my friend Brian Knight and I wrote a story a while back called "The Dead Letter Office," about a guy who literally evolves into a post office. It was being considered for Tom Monteleone's legendary Borderlands anthology series but it seems the series is having trouble getting the next one to go. So, after oh-so-long it's been sent somewhere else. Guess we'll see.
Brian Knight is an awesome writer and an awesome guy and it was fun working with him. Do yourself a favor and check out some of his work.
