Heed the Thunder by Jim Thompson

In the rural town of Verdon, Nebraska, in the early days of the 20th century, you can't go ten feet without running into one of the Fargos. So, Grant Fargo argues to his grandfather Lincoln, it's perfectly all right that he's desperately in love with his first cousin, Bella-she's the only source of intelligent conversation for miles, and in a town like Verdon, it would be hard not to end up with a relative of one kind or another.

 

Before it all plays out, men will be murdered, jailed, tarred and feathered or worse, and while everyone in the Fargo clan would kill for the family deeds, God might just end up with them instead. In Heed the Thunder, one of Thompson's earlier works, Thompson's signature style collides with a sweeping picaresque of the American prairie, in a multigenerational saga that's one part Steinbeck, two parts Dostoyevsky, and all Jim Thompson.
