Heard: Deadman's Road by Joe R. Lansdale, 2010, the Overdrive.com edition says it was available in 2014. I'm not sure if the 2014 date is a pub date for the audio or the date available through purchase with Overdrive.
Several novellas of Reverend Jedidiah Mercer who travels wild west Texas fighting demons and other evil creatures. Not much to say. There are episodes of Jedidiah fighting evil around the state with vampires, cave trolls, and other deadly beings from hell.
Mercer has been cursed by God to travel the west wreaking Old Testament style justice. Mercer is not happy with God for forcing the job upon him. But, since Mercer was once caught having sex with Mercer's own sister he kinda understands the punishment.
Lots of filthy people. Six gun blasting. Dead horses. Wanton women. An angry Jedidiah Mercer who quickly kills when suspecting danger. Booze. Dust. Danger. So on. So forth.
The real interest in these stories is that Lansdale writes them. If you like Lansdale we'll like this. I liked this.
