Actual, current one is the third book in a four(or five, not quite clear yet) part time-travelling space-opera. I wrote the first book in 2010(!) and I've been working on number three since 2015, but kept getting interrupted/distracted. I've been pulling things back together this year.
I'm currently 310k "in", but there's a lot of junk that probably needs to come out or belongs in the next book, or just needs editing. Because I'm a pantser, and the book has four interweaving POVs, of which three are written and the fourth is part done, how far "in" is a tricky concept. I have written the last chapter, which is the obituary for the POV character I haven't written yet...
There's also 40k of a spinoff/sequel/prequel that I accidentally wrote last summer in between medical appointments, and I keep picking away at that. I'm not quite sure what to call a book that uses a clone of one of the main characters from the main series in a time that's
probably after the main series, depending on what my pantser brain does in book four. As my character tells people, time-travel really messes with your head.
I expect life would be easier if I was a plotter.
