This is the second book in the series, and the second one I read. I didn't remember much from the first book, and I don't think it's necessary to read it, but it's probably better if you have.
Although I wouldn't want to live there, the author makes these Kentucky backwaters sound somewhat appealing in a lot of ways. The people are, for the most part, pretty backward, the living conditions are mostly backward and run down (as are the people), but there's a directness and honesty about them that you don't usually see in the big cities. I don't know if they would act the same toward strangers, but if you're from around there, they feel more comfortable around you. So, Mick Hardin, who finds himself investigating crimes sometimes for his sister, the sheriff, the first thing he does when talking to someone is to state his name and his father's name, and maybe his grandfather.
Mick is very nonjudgmental. He's slow to disagree with anyone, knowing it could lead to trouble, even generations of conflict. He thinks everyone deserves to live, and doesn't even like to kill people who are after him. He's a pretty serious guy most of the time, and doesn't waste words, but there's a dry humor here and there that I like, same as some of the other locals. Overall, he's smart, stubborn, and often his own worst enemy. But I think he'd be a good friend to have.
One illustration of his way of doing things... there was one place where a drunk employee in a department store had a gun and claimed to have hostages. He wanted money in exchange for releasing them. Mick was there, so he got a bag, filled it with napkins from the store, added some bills from the cash register on top, and went in to talk to the guy. Found out there were no hostages, and the guy mainly wanted the money to buy something his girlfriend wanted. Mick talked him down and when the guy asked what he could say to his girlfriend, Mick told him "The truth. You did it for her. She'll appreciate that. It's what they call a grand romantic gesture. You did your best".
Before leaving, Mick took $4.00 out of his wallet and left it to pay for the napkins, and returned the bills he had used for the ruse to the cash register.
The book has a bit of violence and killing in it, but not as over-the-top as some others I've read lately. It's hard to really work up a hate for most of the bad guys, even the ones that kill people. Not that you especially like them, but Mick even feels bad about the ones he has to kill, mostly.
