Kindle Questions

[ithildin]

So I'm trying to put books on the Kindle we got mum for Xmas. She loves romances, so I thought I'd get her a Harlequin subscription, and bought a single book as a test. I read through a bunch of stuff and chose the Adobe PDF version since Kindle supports PDF files. Except after I bought it, I found another FAQ that says they can't be read on a Kindle. Is there some sort of conversion program? I know I've read that people put there fanfic on a Kindle, so I'm hoping :)
