I know you didn't ask me -but kindle unlimited goes on sale a few times a year (amazon's july event and before black friday are two times I know of) where you can sign up for a year or two years at about 50% off. I think there is or often will be free trials offered so you can try it and see if you can find anything you like. I have had it in the past = there are a lot of really bad books out there with truly awful writing, but every so often I found something I liked. I would try it at a discount or free trial first.
For example this one has expired - but it has popped up several times in the recent past:
