The Ark Part 2 is progressing and currently at 25 chapters and over 200K words. I am projecting 30 chapters and about 300K words at completion.
The story is rather complex with around 10 ongoing subplots that are interrelated and presented chronologically.
Continuity checking the subplots and relative timing between subplots will be a major editing effort. I sent the first 5 chapters to my editors today.
I expect the story to be fully written, edited, and ready for posting this January, if all goes well.
