Judging by the common (often quoted to me) yardstick that says 50,000 words equals a full novel? Book 6 in the series is 3 novels -- 150,436 words! Next important date, beyond the finish date is the 6th, for me. It's about then that I expect to start work with the cover artist to pull together the cover for this book! And, of course, you'll get sneak peeks as the cover is in development.
Meanwhile I'll be writing the back cover blurb. Writing... and rewriting, I suspect! Because I'll also have to make sure that it's suitable for the critically important Amazon description. I was told recently that the descriptions I currently write are too complex to be compelling, so I'll be working hard to get this right. Please wish me luck!
