Amazing Thriller Books Free on Kindle Unlimited
First off, I should point out that if you have had your Kindle for a while, OR you want to try one, now is a great time to shop, as July 8-10 is Amazon Prime Days.
Kindles are about the only thing I buy during these sales, and this year there are some very affordable options. I save money by getting the ad-suppored version, and that doesn’t bother me at all. It’s all book ads!
The Entry Level Kindle (16 GB) is only $84 (20% off with a trade-in)
Or the newest Paperwhite (which comes in jade, black or raspberry) is $124 (and 20% off with a trade-in)

Man Made of Smoke by Alex North

The Last Flight by Julie Clark
So interesting and discussable! If you missed out on this during the pandemic, now is your chance to try it. My lively Spoiler Discussion of The Last Flight is here!
All the Sinners Bleed by SA Cosby
I’m shocked this is on here! This book was on multiple major “best of 2024” lists. It’s gritty Southern noir about small town prejudice, family, and justice. Check out my Review of All the Sinners Bleed!
Last One at the Wedding by Jason Rekulak
Perfect for fans of Harlan Coben, this dad-to-the-rescue book had a lot of charm. Check out my Readers Guide to Last One at the Wedding.
Beyond Reasonable Doubt by Robert Dugoni
If you loved Law & Order and enjoy “ripped from the headlines” books, check this one out, then come and read my post that outlines the similarities to a real case!
A Very Bad Thing by JT Ellison
This book tends toward the wacky, but if you secretly love soap operas (like me) give it a try. It’s very entertaining with tons of twists and turns! Check out my Readers Guide to A Very Bad Thing.
Little Secrets by Jennifer Hillier
This was such an interesting and twisty book. It does deal with child abduction, and that may not be for you, but I definitely recommend it. It’s a classic psychological thriller! Here’s my Spoiler Discussion post!
