The wrong book?

Well, there I was, innocently going about my life, and through a variety of sources, I started getting a teeny tiny little message-The Book? I'm writing the wrong one. Yes, God wants me to write That one, but there's another one to write too. One that must come first. I think. I don't have a lot in it yet, the other one is longer. I'd write more about it, but my wrists are killing me, sad to say. And given that I didn't sleep last night, just a couple of naps today, my brain isn't working all that well either.
