Sometimes there's a couple of the books worked into a season. But mostly focuses on one novel. Of course there are subplots running through the entie=re series of the novels.For those of you who watched Bosch, does each season just follow one case? My wife doesn't have patience for that sort of writing , lol. She likes to see things wrapped up in one episode like NCIS for example. Or Blue Bloods. A side plot threaded throughout the season is okay as long as it doesn't dominate but as far as she is concerned. "lets wrap this up"!
