It’s that time – Amazon’s best 99p Kindle book deals are live for September 2025, and there are some absolute gems this month! Whether you’re building out your summer reading list, or just need a new book to escape into during your commute, you’re in the right place.
This post will be updated monthly to bring you the best 99p Kindle books available to UK readers, handpicked to suit all tastes. From gripping thrillers and heartfelt romances to mind-bending points of view in sci-fi and fantasy, there’s something here for everyone.
[Post updated 3rd September 2025]
After realising that my TBR would set me back thousands of pounds if I were to buy every book on it full price (maybe even tens of thousands!), I had to make some decisions. I have a HUGE spreadsheet where I track all the books I want to read (and further separate them by “really want to read” and “want to read”), and I’m now tracking their prices. I have an alert set so that when anything that’s on my TBR drops to or below a certain price, I get a notification. Sometimes Kindle books only drop to 99p for a day or two, then they’re back up to £5.99 again, so the alert makes sure that I can make sure I’m ready for these. And on the 1st of the month, those alerts often go a little bit crazy!

So I’ve decided to share these finds with you! In this list, I’ll tell you a few 99p Kindle books that I’ve read and personally recommend, those that are on my TBR (so if you’ve got a similar reading taste, you’ll know where to look), plus some of the other 99p bestselling books, including BookTok’s top books and those I’ve heard about everywhere. There are a lot more on this page here – not all 99p, but check it out for some amazing deals!
By doing this, I’ve managed to spend only around £40 on books this entire year despite reading 65 books so far in 2025, and considering that one of those books cost £25, I think I’m doing very well!

TikTok Made Me Read It…
TikTok has become a powerhouse for readers – if you’ve ever added a book to your list because of BookTok, you’re not alone! A lot of the titles discounted this month are trending across TikTok, and let’s face it, if a book has thousands of fans crying, gasping, or swooning, it’s probably worth at least 99p! I’ve included some viral favourites, as well as a few under-the-radar gems you won’t want to miss.

Reading on the Go
Whether you’re reading in bed, on the train, or while waiting in the school pickup line, your Kindle or supported device turns downtime into “one more chapter” time.
Already filled your hard disk with downloads? No problem, Amazon’s cloud keeps your library safe, so you can delete and re-download with ease. It’s the magic of Kindle books – no lugging heavy bags or worrying about losing your page. Personally my Kindle library is an absolute mess (#BookTokConfessions), but I love that everything is all stored in my Amazon device and content section – I’m forever dropping in there to search for books I’ve lost into the ether of my Kindle library!
Share the Love
If you’ve got a best friend who’s always asking for recommendations, send them this post! You might both fall in love with the same story, and a buddy read is even better when you’ve only spent 99p each!
Plus, when you buy using the links in this post, I may earn a small commission at no extra cost to you, which helps support more content like this and keeps the reading list growing as I hunt down the best deals every month.
And if you’re part of the Kindle Unlimited crowd, you’ll find even more amazing titles included in your subscription. Many of the books featured in the 99p deals rotate through Kindle Unlimited, so it’s worth checking if your favourites are available to borrow instead of buy. I have a post coming up very soon on whether Kindle Unlimited is worth it, but you can get a Kindle Unlimited subscription with a free trial now if you sign up here to find out for yourself if it’s worth it for you!
