You need to read Lois McMaster Bujold's Vorkosigan series. The series has 3 books that have won the Hugo for Best Novel and 3 others that were nominated but didn't win. It is one of the best scifi series out there.
Available from Baen. DRM free. Heck, completely free from here.
Go to the Cryoburn CD to find the files.
This is a site that is hosting the CDs that Baen will include in some hardcover books. The CDs are freely redistributable. Baen is aware of the site and while it doesn't actively support it, they haven't asked them to stop.
You can get the complete set of the Vorkosigan books (minus one story called Memory that was forgotten when they made the disc, ironic huh) including the most recent book that had the CD included. That's right, they included an ebook version when you bought the hardcopy.
The files are all drm free and they give you the option of getting the epub, mobi, lrf, txt, html and another format I'm forgetting.
