Try your local library. Many state library's now have free audiobook services where you can download the book straight to your computer an then burn it to a disk. I live in Alaska, and the site here is called ListenAlaska. It is accessible through the municipality library website. Usually you need a library card to check out an audiobook and on average you will get to keep the book on your computer for 7-14 days. It will probably require downloading a program called Overdrive. It's a nifty program. I would take advantage of all the free services out there. Otherwise you can download it as a torrent, but that is more complicated and a little time consuming. Search BreakingDawn torrent in google. You'll have to download software like Vuze in order to process the torrent. This isn't an easy process if you aren't at least moderately computer savvy. If all else fails you can download Audible or Itunes books for a discounted price. If you choose to go the torrent route, comment on this post and I will walk you through it.
