From one book lover to another, these are 13 of the best Kindle book deals live for October Prime Day

Amazon sales like Prime Big Deal Days are one of the best times to buy a Kindle on the cheap, but they can also be a great time to pick up e-books.

For the first day of the two-day event that is Prime Big Deal Days, Amazon has marked down tons of e-books, from self help to fiction and children's books, for prices as low as $1.99.

The sheer number of books Amazon marked down means you'll likely have to do a little digging to find what you want to read — but to make your job easier, we put together a list of 13 of the best Kindle book deals available so far. (As a note, these markdowns are in comparison to the regular print prices of these books). Check them out below, and be sure to check out everything else on sale during Prime Big Deal Days and follow along with our live blog.

Why we like it

Obviously, taste in books is very personal, but for anyone out there who likes decade-spanning series about the complexities of female friendship, the Neapolitan novels fit the bill. You've probably seen this book recommended before, but I have to add my endorsement. When I finally picked up this series earlier this summer, I found myself unable to read anything else until I finished all four books — currently, my friend who I lent the first book is in the same cycle (and for anyone who's read the series, yes, we do text about how much we hate Nino).

Basically, if you've read or are planning on reading the first one, I'm willing to bet you'll be in need of the fourth one at some point — might as well get it for $3.99. And when you're done reading the books, you can check out the show.
