Ok I have just about had it with ebooks and the ipad. I can never get my ebooks to sync unless it's one I buy from the itunes store. To be honest, there are cheaper out there and I can get a lot more availability elsewhere and I should be able to do this, so I'm not feeling to charitable towards Apple about it.
So I have a folder of books on my pc (Windows 7) I use to store my books in. Tonight I added 'A Game of Thrones' in .pdf form and it didn't work. All I got was the book with the little download bar across it, but it wouldn't progress, it just stayed black. I converted the .pdf to an .epub using an online service and got the same results. The book shows up on the Ipad, but the download will not progress.
