Ups, you're right. I didn't check the titles, only that after I copied it to excel I had one line too many.The numbers are right, The Adversary is #282 both times, I think I spotted the fact this book was in both series and so just put it in a second time to remind myself to go back and look at this one again to see what went on and how it effects the second (Brimstone) series.
Also after comparing your latest list to mine I found that the differences are only due to me being an elitist who only counts what I consider "real" FR novels. So I excluded stuff like those Abyssal Plague novels (exept for the single one that was a FR novel) on purpose and actually didn't even think at all about those D&D story collections that contain a FR story among their collections but are also not FR novels. Now that those are brougth to my attention I now chose to exclude them on purpose rather than mere neglect
Basically for me FR novels are only those with the FR emblem on their spine () (*) and that line ended with Hero in 2016.
I add the Drizzt novels that have been released since then to the bottom as sort of "honorable mentions", but I actually haven't read any of them yet.
(*) also not 100% true, as I do count the Tymora's Stone trilogy which strictly speaking doesn't bear that badge of honor on the spine
(**) and of course ebooks that were officially released under the umbrella of the novel line even though they don't have any spines at all
