This is fully of gritty or sassy dialogue, reminding me of the hard-charging series that I've been very much enjoying, "Hell Divers." But instead of the hell of dealing with alien (well, future-earth) monsters, this book has its human monsters and the kind of thrill-ride that that creates.
The men here can be a bit sexist, I think, not surprising in a day and age when it's pretty obvious that that stuff still, alas, goes on, despite all our past hopes.
The procedural here with gasoline and photographs and evidence may carry the weight of the story, but the characters and their relationships made it interesting.
You definitely get the feeling that our heroine is someone with a past, someone with a history and damage that informs the person she's become.
