I am reading a bunch of free novels on my Kindle. It's been my project for about a year now. For a few years, I used to regularly "purchase" free promotional books from Amazon. Then one day I realized I had over 1000 books that I wasn't actually reading. So I have been going through, re-evaluating synopses, deleting a whole bunch that no longer sound good , and trying to read the ones that still appeal.
Right now, I'm mildly enjoying a YA series called The PSS Chronicles by Ripley Patton. Got the first one for free back in 2013, read it today, then suckered myself into buying more. Apparently ebooks are essentially sold like drugs. First hit is free to get you hooked.
