Coming soon! Cozy Mystery new releases for September 2025

Cozy mystery new releases for September! Ok, seriously, WHERE did my summer go? How is it already September? *sigh* I hope you had a great August and read some great books! I am (again) behind on my reviews but maybe September will be the month to catch up! LOL. But in the meantime, I’m adding a whole bunch of new books to my TBR – which ones are you looking forward to?

As mentioned in the August new release post, I’m now only including new releases I find on Netgalley, releases promoted by their authors/publishers in newsletters and on Instagram, OR releases an author emails or DMs me about.

If you have a book coming out and would like to be included just reach out to me on social media (@bookfrolic on Instagram or Bluesky is best) or via email at stephanie@bookfrolic.com. So while this list is MUCH shorter and I will accidentally leave out many great books (sorry!) it saves me a lot more time doing things this way, so I hope you’ll understand. If you spot any cozy mysteries that were left out of my list, feel free to leave a comment and I’ll add it to the post!

Leave a comment and let me know which books you’ll be reaching for this month!

If you’ve found this list useful, please consider supporting my blog with a tiny donation! It takes me several hours to put together a list like this and since I do not have ads or affiliate links on this site, every bit of your donation gets put right back into the cost of running this blog (web hosting, domain fees, etc). Thank you so much! xo ~ Stephanie

Book info, including release date, was correct at time of posting, but may change at any time.
