I’ve had Kindle Unlimited now for about a year, and even though I don’t get a chance to read as much as I would like, I definitely think it’s worth $9.99 a month, especially if you’re an avid reader. Ideally, I wish it was maybe $5.99 or $6.99 a month, but if you read just one book a month, you’ve basically made up the $9.99 cost. I suppose you could argue that you could just go to the library and check out the books for free, but the library also doesn’t have the vast amount of titles that Kindle Unlimited seems to have. Also, you could use the lending library feature of Amazon but I think that only gives you access to one book at a time, whereas with Unlimited you can have up to 10 books at a time before having to turn one in.
With that said, I’m trying to keep track of medieval books I run across that i might want to read later. I plan to start posting my findings here on my site. Since I was recently reading about the Third Reich and how the First Reich began with the reign of Charlemagne, I thought I would see what books Kindle Unlimited has regarding Charlemagne. Doing a brief search for Charlemagne filtered only by Kindle Unlimited books, I came across this listing.
