The Apple Books Store is another big-name ebook retailer with a nice selection of free titles. For those who enjoy indie books, Kindle Unlimited could also be a good investment - it’s $9.99/month, so not quite free, but you’ll gain access to over a million titles and there’s no cap on how many books you can read per month. If you’re seeking free Kindle books, you’re in luck! The Amazon Kindle Store has two sections dedicated to just that: its Free Popular Classics page and its list of Top 100 Free Best Sellers.
