The westerns and horror genres go well together. There’s actually a long history of mixing westerns with the fantastical (typically horror). Enough so that it is a long established sub-genre, the weird western.
In 2020, Death’s Head Press launched their Splatter Western line, emerging and established horror writers writing westerns.
I wrote a bit about the history of weird westerns and reviewed the second Splatter Western title, Hunger on the Chisolm Trail, earlier this year.
The series is worth your time and, just look at these great covers!
