Usually I read three novels before approaching to write one. There is logic in taking in as much as you can or as much that is needed without distorting your idea for a long piece. But then again if you read excellent novels for prep, what has inspired you from those could likely mold the potential of your own work--no matter what style or genre. I'm a romantic buff. Whether it be crime or mystery, my plot always stem from or guide me to mutuality.
