It used to be that female sleuths were ex-police and now private detectives like Kinsey Milhone and VI Warshawski. They were hardened, athletic, loners and very professional. Now any line of work provides female detectives. There are chefs and caterers, knitters, herbal doctors and now a fishing boat captain that takes tourists out. And, oh yes, on the side she solves mysteries.
Randy Wayne White has a series of novels featuring Doc Ford in the western Florida Islands. He now has a female protagnist. The problem with Hannah Smith is that you are painfully aware it's written by a male. First of all, there is a lesbian pick-up scene that just doesn't fit. It's just sort of plopped there without any context. This is clearly a male fantasy. Second, the character is always frightened and whenever she achieves something it seems to be accidental. She fumbles around and loses her gun. It falls out of her pants pocket. Really? Third, the villian is a man who controls women through degrading sex. This was clearly a man's view of what women are like.
There was not much of a plot and virtually no mystery. You know who the bad guy was immediately and there are no red herrings. There was plenty of descriptions of a yacht that held sex parties on it. There was a lot of men degrading women. There was a lot about fishing boats. There was just nothing to really hold your interest. If I hadn't been reading it for Amazon, I would never have finished this drivel.
