I have the first five novels in that series, and now I'm torn as to whether I should read them or not. I got them used about a year ago, but I haven't even opened them up yet. I'm sure one day I will read them, and then I'll be all sad when I get to the last novel and realize it is unfinished.

Perhaps they could half-ass it like Frank Herbert's son did with the Dune series. He finished out the last novel using his father's notes. He also wrote several prequel novels in the process.
