I can't remember if I mentioned this, but a week or so ago I added all my books to Kindle Unlimited. If you aren't familiar with Unlimited: for $9.99 a month, you can essentially rent books from Amazon's site via pc, table, phone, etc. It's basically the same idea as a library/Netflix, but it is something to consider if you are a fast reader. Personally, if I had the time to read like I did when I was single I would be all over this service. I would read a book a day or every other day. Let's just say it was a tad expensive.
Currently, Unlimited is (heh) limited to the USA. According to Amazon's site they plan to push it internationally, but I think they are using us as the testing grounds.
In any case, they are on amazon and if you have Unlimited, please check the series. Here's a link to make it easier.
