Goodread logoGoodreads is the world's largest site for readers and book recommendations. Their mission is to help people find and share books they love. If you're looking for a place to discover a great book or to discuss your favorite books with a community of readers, you've found the right place!

Not only can you find book recommendations, but you can also track books you've read, enter reading challenges and see what your friends are reading.

It also allows readers to sample certain books or, in some cases, even read them in their entirety for free. ... As Goodreads outlines on its site, Preview is available on any book that has a Kindle edition. All you have to do is navigate to the book and click on the “Open Preview” button.

Goodreads is a completely free site, so you won't need to pay to access the site or app, unless you're an author who is creating a giveaway.
