Last year, I signed up for Kindle Unlimited, but because it was a bit tough to weed through the wide selection to find great Kindle Unlimited middle grade books, I hardly ever used it. Also, I get an overwhelming number of eARCs (Advance Reader Copies) these days so it’s rare that I’m reading a book I actually bought on my Kindle. That said, I’ve done most of the hard work for you by sifting through the current offerings (these books may be taken off the list every six months to a year). If you have a Kindle Unlimited account and are looking to find immersive stories about tweens, this is the list for you.
