I like many authors. Often, the ones who have past are found through my readings of classic books. Sometimes, I saw the movie version of a book and picked it up. Alot of books were recommended or discussed with others. I know a friend who shares my interest in Nick Hornby, another who loves E. M. Forster as much as I do.
As with most things, it was love at first sight mostly. I tend to know what I like and feel my way first. Some authors grow on me to be sure though.
