Kindle Unlimited has an ever-changing library of titles, so don’t expect to see the same books available every month. This is a particularly good choice if you’re looking for a vast array of titles to choose from, but you're not buying or owning books here, instead you're renting them, a bit like a library.
This service offers a huge selection of books directly from Amazon’s library, all included with the subscription. Want a free trial of Kindle Unlimited? At the time of writing you can get it free for two months, while it normally offers a free month and then costs $9.99 / £7.99 per month after that. Below are some of the top stores we've used for free books: Self-published authors often put their titles on these stores for free as well, so they're a great resource that will allow you to get free books onto your Android phone or tablet.
