Rach's Reading Club

You can choose a book you know is action/adventure and look it up on Amazon, then see where it's ranked in that category, then click to see the top 100 selling books in that category. That should contain something you'd like. Or find that category on Audible and sort by top rated. Good luck finding stuff you will love! I checked and here are some ideas I found...

Project Hail Mary by Andy Weir (rated 4.9 on Audible--already in my Audible Library)
Last Summer Boys by Bill Rivers (rated 4.8--added this to my Audible Wish List lol)
One Good Deed by David Baldacci (rated 4.5 stars--turns out a LOT of action & adventure books are a part of a series, but at least this is book 1 in the series)
My Killer Vacation by Tessa Bailey (not out on Audible yet, but rated #2 in Romantic Adventure & Adventure, #5 in Thriller & Suspense Action and #6 in Mystery Action & Adventure on Amazon--note that it's really hard to find a PURE action/adventure book, so even the ones I listed previously tend to be a mix of something else--fantasy, military, etc.)
The Omega Factor by Steve Barry (4.7 stars)
The Primal Hunter by Zogarth (rated 4.7--part of a 2-book series, so if you like the 1st, you should like the 2nd since it's rated 4.9 stars--I added both to my Wish List)
Portrait of an Unknown Woman by Daniel Silva (not rated on Amazon and not yet out on Audible, it's rated #1 in Women's Adventure Fiction...didn't know that was a genre...and #5 in Crime Action & Adventure--I added it to my Wish List)
Armored by Mark Greaney (rated 4.5--Already on my Wish List)

Anyway, I hope this helps! Good luck finding things you'll like!
