book franchises w present fanbases

can someone suggest some popularish YA franchises/standalones that have large and present fanbases? i cant read books i cant discuss and read abt online later lol

ive read the classics, ofc, like agggtm, shatter me, hunger games, caraval, leigh bardugo, etc

can you recommend some along those lines? i want to be able to see lots of edits and discussion posts/reels after i read so thats basically what im looking for (in YA preferably)
