Kindle Unlimited is a monthly subscription that unlocks a vast library of eBooks, magazines, and a curated selection of audiobooks.
Once you're signed up you can borrow titles with no due dates, and keep up to 20 on your device at once.
It works on every Kindle device, as well as the free Kindle app on your phone, tablet, or laptop, allowing your to reading to sync across multiple devices, and download content for offline use.

No, you don't need a Kindle device to use Kindle Unlimited.
The membership works for free via the Kindle app for phones, tablets, computers, and other compatible smart devices, so you can read at home or on-the-go.

Amazon says members can access more than five million titles, with a mix of chart-toppers, cult-favourites and Amazon Publishing exclusives on the lineup.
This includes eBooks, magazines, comics, and a growing selection of audiobooks.

You can also visit the Kindle Unlimited page to browse by category and top picks, making it quick and simple to find your next read.
Following the 30-day free trial, Kindle Unlimited costs £9.49 per month.
Once your free trial has ended, this is how much you'll be charged unless you cancel, as the membership will automatically roll into a paid plan.

Plus, alongside this free 30-day trial, Amazon is also running a two-month subscription offer on its site.
You can get two full months of Kindle Unlimited for £3.99 instead of £18.98 with the offer, which will renew at £9.49 per month afterwards.
No, if you've got an Amazon Prime subscription, this doesn't include Kindle Unlimited, it's a separate paid membership.
But you also don't need Prime to sign up to Kindle Unlimited, you can sign up to just this subscription and enjoy millions of free books.
Prime members meanwhile do get Prime Reading included, which is a smaller, rotating library of eBooks, magazines, and comics.
While Kindle Unlimited is the bigger upgrade, offering access to over a million titles, while Prime Reading includes a little over a thousand, with some overlap between the two catalogues.
