Sometimes there are books with content that doesn't reflect your "what you're all about" spirit. Sometimes the material comes out just too funny...now that would be an awful thing to have stick. High expectations can be a bitch.
In this case, none of that was at issue, so why I chose to write under a pseudonym? Well, you'd have to ask Marlie, but until then, I'd offer that you can't judge a book by its cover.
Live long and laugh.
