A long time ago i was reading Stephen King's The Dark Tower series. I was asked if i was a Stephen King and i said i was not. A fan of Stephen King would finish The Dark Tower then go on to read his other books, Carrie, The Stand, Salem's Lot, From a Buick 8 etc. I never did, after i finished The Dark Tower i moved on to Arthur C. Clarke's Odyssey Series and when i finished that i went on a reading hiatus for a few years.
So you see what i mean? there is a difference between being a fan of the author and being a fan of a particular book/series.
The first time i actually read an 'author' was with Isaac Asimov mostly because a lot of his work is actually tied together so in a way its like one very long series.
What about you?
