What really long book series have you read every single book of? (not counting rare or hard to find stories or out-of-print stuff. Off the top of my head my list includes:
>Culture (including State of the Art)
>Thomas Covenant (and Gildenfire) + Gap Cycle
>ASOIAF
>Pliocene Epoch/Galactic Melliue
>Book of Words/Sword of Shadows (book 5 wen?)
>Redwall (Excluding those weird pop-up books)
>The Dark Tower (not the comics tho)
>Dune (yes the shitty sequels his son and Anderson wrote too)
>Remnants/Everworld/Endling (working on Animorphs rn)
>His Dark Materials
>PJ Farmer's The Dungeon
>The original Sword of Truth books
>The Gandalara Cycle
A few more I can't think of right now, I'd have to check my goodreads
I'd be interested to know what book series other anons have read and enjoyed. These threads have gotten so stale and I'm dying to talk about good sci-fi
