The Wheel of Time series. I bought the first 4 books in the series and got like a quarter or a third through the first book and stopped. It was a bit slow and I kind of fell out of reading in general for years. Recently I started reading a bunch of different books but have been put off of restarting the series because of how many books are in it.

Funny backstory, I wanted to read a specific series that I knew was highly rated but I couldn't remember the name of it except that it had something "round" in its name. After some searching I came to the conclusion it was The Wheel of Time series with the "round" thing being the "wheel" in the name. As I got a few pages in I thought to myself that this was not what I was expecting and started to suspect I made a mistake in what series I originally wanted to read. I did some more searching and then remembered that it was Disc World that I wanted to get into.
