I don't ever stick to one or a pair of authors. I have read books created by an author that I thought was mindblowing and then checked out some of their others which I thought were total crap. There are very few authors that I see who are capable of consistently creating smash hits or keeping my attention so I'm constantly going from author to author.
But like I said there have been some authors that have been able to hold my gaze. Those being the Christopher Paolini (Eragon, Eldest) J.K. Rowling (Harry Potter) and JRR Tolkien (The Hobbit, Lord of the Rings).
