Most popular authors have a certain style, subject matter, or quality of work that others come to depend on. So you say X, and people know what they're getting. But are there current authors or historical ones that have produced works that vary wildly in terms of quality or subject or whatever? I mean like one getting very good reviews and another very bad reviews? Or one dealing with the life of a saint or a major respected public figure and then one about the life of a pimp?
