I started following the Summer Camp stories by Nick Scipio in either 2002 or 2003, intrigued by a prologue before the first chapter that set up the main mystery in the stories - Who is the Wife (of the MC)?, and Who Died? (somebody important to the MC).
It's now 18 or 19 years later and the summer camp stories, as far as I know, have not concluded. Still not revealed are Who is the Wife and Who Died. Last time I looked, real time (18 or 19 years) is moving faster than story time (not sure - it has covered maybe 10 years, more or less, of the MC's life, from high school to sometime in college).
originally, the author promised the complete story would be told in 3 "books". Now he's working on the fifth book and the first four of those are on SOL. I thought I remembered a promise that he'd eventually post Book 5 on SOL - but I've seen no signs that he will (or won't) do so.
The question: How patient are you for an author to finish the story arc set out from the beginning? Is 18 or 19 years just about right, or should it take 25 years or more?
