Auto-Buy Authors

As you've no doubt gathered, this is a post about the so-called auto-buy authors - though for me, I guess they're more of auto-borrow-from-the-library-as-soon-as-possible authors. For those of you who haven't heard of this term, an auto-buy author refers to those authors whose books you will buy/borrow instantly, no questions asked.

I have a rather short list of true auto-buy authors, those whose books compel me so much that I would fight my way through seven feet of steel to get to them. The number one on my list is John Green, whose books and vlogs (with his awesome brother, Hank) I adore.

The other two are Markus Zusak and Erin Morgenstern (although she's only written one book. I'm pretty sure the reasons are self-explanatory!

Who are your auto-buy authors?
