I finished the sequel to Zeck today. I still have to give it one more revision, to polish up a few rough edges and catch as many typos as I can, but I can confidently say that today, I finished writing Zeck vs Colonel Destroyer.
This is super exciting to me, because I've been working on it for almost exactly two years. I released Zeck into the world in late October of 2015, and started working on the sequel during NaNoWriMo of that year, which starts November 1st. I tend to do NaNoWriMo in odd-numbered years, and finishing this book so I can clear time to work on my NaNo project is a huge relief.
Mind you, if I hadn't finished by November 1st, I'd still have kept working on it until it was finished. I didn't rush the novel to completion just so I could get it out of the way. It took the time it took, and it became as long as it needed to be, which is nearly three times as long as the first book. (Still fairly short, but novel length rather than novella.)
Longer post on all of this later. Right now, I need to shove some food into my mouth after sitting in a dark room in front of a keyboard for hours.
Zeck vs Colonel Destroyer should be out in mid-to-late November.
