Just for fun: Another question

Okay, my question yesterday got me more responses than I've possibly ever had to a post! So another question for you:

Which, if any, authors do you buy 'sight unseen', meaning which do you see they have a new book and immediately buy it without seeing reviews, hearing what friends think, perhaps without even reading the blurb?

A couple for me:

• Patricia McKillip - I've loved her clever, literate fantasy novels since reading the Riddle Master books as a teenager
• Terry Pratchett - the quality can vary but I'll always buy them anyway
