I'll start us off:
"Hell Hole." the 4th of Chris Grabenstein's 'John Ceekpak' novels is $4.95 for paid Audible members (including Light).

As a Jersey boy* who spent a lot of time down the shore, I've enjoyed the first three of these cop stories, and though I'm not crazy about how Grabenstein is starting to soapbox his personal politics, or how dark I fear the stories are getting, I'm willing to try one more at that price.

*Book three had a scene set right near my house. I was actually driving by the place as I was listening to it. I got a huge kick out of that.
