If you're willing to pay $9.99 a month to access over 600,000 ebooks, Amazon's Kindle Unlimited subscription could be what you've been waiting for.

The new service, dubbed a 'Netflix for books,' was leaked through the Amazon US website briefly, before being removed. However, you can still see the page through Google's Web cache, as noted by The Guardian. The webpage highlights popular titles including The Life of Pi, The Hunger Games and Harry Potter.

It is not known whether the service will be available across the pond, but at least for US subscribers, the service will cost $9.99 a month and give you access to over 600,000 ebooks as well as thousands of audiobooks.

In a promotional video discovered by GigaOM, the narrator says:

Kindle Unlimited gives you the freedom to explore over 600,000 titles and thousands of audiobooks in the palm of your hand. Enjoy unlimited reading and unlimited listening on any device for $9.99 a month.

Apparently, users can sign up for a 30-day trial, in the same way that consumers can try Amazon Prime.

The subscription service will expand on Amazon's Prime Lending Library, which allows users to loan one book a month from hundreds of thousands of titles in the US and United Kingdom. Titles include those from the New York Times Best Sellers list and the full Harry Potter series. The service is available on Amazon's Kindle e-readers as well as the Kindle App which can be used on Android and Apple smartphones and tablets.
