Amazon Prime Day is slipping away (officially ending at 2:59 a.m. ET on Saturday, July 12). There's still tons of deals still live on the final day of the event, so if you're looking to stack your summer reading list with books, it's time to get going.

On top of Amazon offering three free months of Kindle Unlimited and Audible to new members, there's also some pretty sweet discounts on books themselves. While we generally recommend purchasing your physical books at local book stores, it's hard to pass up a major discount on books you've been eyeing.

Whether you want to load up your Kindle with e-books or you prefer physical books in your hands, there's a deal waiting for you on Amazon Prime Day, day four. Kindles themselves are seeing some massive discounts as well. This comes as no surprise, considering Amazon owns Kindle. (If you're looking for those discounts, check out our list of the best Kindle deals.)

From bestsellers to hidden treasures, we're tracking all the best Prime Day book deals below.

Why we like it

Physical page turning holds a special, untouchable place in our hearts, but physical copies of books are not cheap. For Prime Day, however, Amazon is giving shoppers the ability to pick up three books for the price of two. That means you can finally add to your physical TBR list without breaking the bank. It also helps, of course, that most of the books are already discounted as well. There are tons of bestsellers, new releases, and BookTok favorites included in the sale, including Sunrise on the Reaping by Suzanne Collins, Project Hail Mary by Andy Weir, and The Seven Husbands of Evelyn Hugo by Taylor Jenkins Reid. Just add three books to your cart from the promo page and the deal will automatically be applied at checkout.

Atmosphere is the latest from the New York Times bestselling author of The Seven Husbands of Evelyn Hugo and Daisy Jones & The Six, Taylor Jenkins Reid. Just released last month, it's already listed as one of Goodreads' most popular books of the year. It follows Joan Goodwin, a professor of physics and astronomy at Rice University, who is selected as one of the first women scientists to join NASA’s Space Shuttle program in the 1980s. The hardcover copy is on sale on Prime Day for $21, down 30% from its list price.
