I've always enjoyed series... from a young age reading CS Lewis's Narnia series and the RedWall series by Brian Jacques. I like well-written series when I can follow characters over long periods of time or even generations as in the examples given. I don't like super dense, describe the color of the spot of rust on the hilt of the sword which by the way, the sword was passed down through 18 pages of back story before we move on. Its one of the reasons I've never read The Lord of the Rings books or the GRRM books, I'm not sure I have the attention span. Not sure this falls into the same bucket as to why I didn't enjoy them but I could never get into the Wheel of Time books, I read the first one and part of the second one and gave up as a teen. In college I started the first one again and never finished. I also read Terry Brook's Magic Kingdom for sale series but could never get into his much more popular Shanara series. I'm fine reading YA if its well written. Not sure if you'd classify Harry Potter as YA or at least not by the end. I'm not ashamed to admit those may be my favorite books ever. I also read the entire Terry Goodkind Sword of Truth series... Arguably those aren't well written (well, they're "problematic" in 2019 parlance) but they had the right mix of reluctant hero is secretly the most powerful person in the world which explains why he's always been so randomly good at stuff and they he's discovered. Any recommendations?
