20 or so books in this series. https://amazon.com/gp/product/B074CGJZ39?ref_=dbs_p_mng_rwt_ser_shvlr&storeType=ebooks
Again, I used to be on board for such things but since I began my writing setup? A series should have a stopping point. Its just what I prefer nowadays.
Side series or anthologies to expand are alright. If there's a desire on the writer's part. But I want the main sequence to have a natural stopping point.
Another example is Harrington. I do love that series but it got so sprawling that unless stated otherwise: Which was a main book vs side story book. #books#scifi#series that go on and on.
