Writing has generally been a process of discovery. Recent discoveries mean that new elements have appeared in The Blind House (working title). Running with it will require going back to the plot and spending some time working the new things in. It will mean taking it all apart, adding the new arrivals, and putting it back together again.
This major change requires another 40 hours. So, that's why my Pacemaker counter is going to go from 14% complete in mid-May 2019 to whatever it will be when I add another 40 hours to the estimated completion time.
Achieving about 1% a day felt good. Adding 40 hours will slow things down a bit, but it should make a better, bigger, deeper novel.
The Blind House might be even more fun to write than The Chair, which will hopefully translate into an enjoyable read for you guys.
