If any of the titles garnered starred reviews in the four library journals, that is indicated after the plot summary of the title. Amazon does a good job of coming up with these monthly lists and especially its year-end best list.

It seems like there will be only one mystery list from amazon going forward, where in the past there have been two – best series books and best standalone books. I’ve read two of these ten books – CLOWN TOWN and GRAY DAWN – both recommended. Big books by Dan Brown and Robert Galbraith (J.K. Rowling) should attract many buyers.

Amazon Editor’s Picks: Best Mystery, Thriller & Suspense – September, 2025

SEVEN REASONS TO MURDER YOUR DINNER GUESTS, K. J. Whittle (Sourcebooks Landmark, $17.99, September). Seven strangers meet for an anonymously hosted dinner party. As the evening winds down, seven cards appear, one in front of each of the guests. On the card is a number – the age at which they will die.

FORGET ME NOT, Stacy Willingham (Minotaur, $29.00, August). Twenty-two years ago, Claire Campbell’s older sister, Natalie, disappeared shortly after her eighteenth birthday. Days later, her blood was found in a car, a man was arrested, and the case was swiftly closed. In the decades since, Claire has attempted to forget her traumatic past by moving to the city and climbing the ranks as an investigative journalist… until an unexpected call from her father forces her to come back home and face it all anew.
With the entire summer now looming ahead – a summer spent with nothing to do in her childhood home, with her estranged mother – Claire decides on a whim to accept a seasonal job at Galloway Farm, a muscadine vineyard in coastal South Carolina less than an hour away from where she grew up. At first glance, Galloway is an idyllic escape for Claire. A scenic retreat full of slow-paced nostalgia, as well as a place where her sister seemed truly happy in that last summer before she vanished, it feels like the perfect plan to pass the time. However, as soon as Claire starts to settle in, she stumbles across an old diary written by one of the vineyard’s owners, and what at first seems like a story of young rebellion and love turns into something much more sinister as it begins to describe details of various unsolved crimes.
