Wot The Fsck You Say, Spotify?

Edit: A couple times I've said eBook while I actually meant Audiobook. I've learned that Spotify has a 15 hour limit per month for their free 'included in premium' audiobooks. However these are the two books I listened to for free, and even rounding up to 13 hours it doesn't make sense, unless they count accidental chapter skips which weren't actually listened to. But it's clear now that I know about the 15 hour limit, that they are not counting the time listening to paid audiobooks.

First book I listened to for free:

I purchased 3 eBooks in the Hitchikers Guide to the Galaxy series (2 came free) and I'm on the final book. 20 minutes left in the last book and this is what Spotify tells me.

I'm over the edge now. I've been putting it off too long. I have a nice NUC I purchased about a year ago.

I'm tech inclined, 20 years of hobbyism, know the linux command line well. Work in IT consulting. But I'm busy. Very busy, and unmotivated to do things like hours of research and toying with settings getting things to work, if I ever have the time.

But this is the start of my new personal revolution.

I'll read the wiki and have read about Sonarr, etc, and I also want movies and shows, but is there anything specifically for eBooks? Looks like Readarr is my best bet? Stripping the DRM of already purchased (and free with Spotify 'Premium') books to share on a seedbox is also something I'm willing to take requests on. Is there a way to rip from Spotify if you have a premium account? And what's the best Android eBook reader (the last 3-4 I tried sucked with pirated eBooks)?

I know I'm sounding like a noob asking everything to be handed to me right now, but I am willing to put in the research and welcome and highly appreciate anyone with tips to point me in the right directions.
