Well, I think of the relaunch novels as both 8 and
9. That's why I named my stuff 10.
Season 8 covers Avatar
, which is the first arc of the books, the "Federation/Parasites" arc.
And season 9 is Unjoined
to The Soul Key
, the second arc, the "WoDS9/Iliana" arc.
Bearing in mind of course that this is just how I chose to think of the books, and the actual writers/editors of the books are not fans of the idea.
