I might make a guess what the chapter count would be, but who knows how many pages. The whole story has been written in outline form clear to the end (that was the easy part), but the words come a chapter at a time. You can thank my computer for the timing on Ch. 13; it would have been up last weekend had the power supply not blown a fuse (this is why I love backups).
Consulting my notes, I find that future chapters will see Charlie and Lionel moving to the Keeler terminus and -- much to your consternation, Taylor -- the return of Laurie Holden, who does not get run over by a truck but lives for several more reappearances. Don't worry, she's not near so infuriating the second time around.
