What with Christmas just around the corner I think I'll order 100 cheap copies of The Darkness that Comes Before and 100 cheap copies of A Game of Thrones, bind them up with ribbon with Martin in the front and hand 'em out. Or leave a "free holiday gift" box outside my office.
I think Martin is the biggest, easiest way to make Bakker converts. Although, I almost want to put the Judging Eye in with it. I know it sounds like blasphemy, but I think a lot of readers might benefit from starting there.
