A key thing that has come out of my writing conferences this summer is that publishers prefer series to standalone novels in the Mystery genre. This leads me to a couple of questions:
1. Do you prefer to read about the same characters over and over, like Harry Bosch or Dave Robicheaux, or do you like the odd standalone, i.e. T Jefferson Parker or Elmore Leonard?
2. Does the setting of the book matter to you? Is it Cabot Cove or New York City that floats your boat?
3. Do you prefer reading a first person or third person mystery?
I started out with a NYC novel as part of the 9/11 healing process. My intention was to write a novel set in Columbus, Ohio next, but I've scrapped that one to write a sequel. My first book, unReQuiTeD, is a first person/second person, mixed POV. The next one, Patron Saint is straight first person. I find it very difficult to write in the 3rd.
My thought now is to work in trilogies.
