The decision has been made. I am going to publish.
The one novel (out of the three I am currently working on) which has been finished is currently undergoing a heavy revision (to purge a forced-in theme that allowed me to give the book a gimmicky title, which has been changed) and when that it done I am going to sign up with CreateSpace and publish my first novel.
I imagine that this will be a lengthy process (if for no other reason that I work very slowly) but I will keep you all informed of the book’s progress.
P.S. I suspect that having a “real” book with an ISBN and everything – even if I don’t sell a single copy – is going to make me insufferable. You have been forewarned.
