I've read dozens. A lot of good ones over on Royal Road. Writing on RR goes from polished professional authors to fan fiction.
I started one a few months ago:

The beginning is a bit of a hot mess, but it's getting better as I go. Which is the main reason for writing again. I need the practice to improve. I do 3 chapters a week for about 10k words. Some people are more, some less.
Many of the books written serial style then get tossed to amazon
app on Kindle.
