I really enjoyed reading William Martins "Back Bay" and "Cape Cod" but, I dont go for a book simply because its about the area. I could read about anywhere, as long as its a good read. I dont think they have more of my interst if they are of local flavor but, I'm sure there are many I haven't read yet, so I wont say for certain.
I feel the same way as many above about those mistakes many authors make by getting things wrong....they make you nuts. I particularly dont like incorrect factoids, directions, etc. books because it interputs the thought process but, movies pretty much make me crazy too.
There was a movie made in the city I grew up in and when I saw the film, I couldnt believe it..had NONE of the feel of the town, nevermind anything else. Its dissappointing to get your hopes up like that.
