The eBook reading option isn't a feature of the Goodreads website at this time. It is only available on the mobile apps. You can mark them as want to read, but you can't actually read them. And then, there is the question of "if there is an eBook available on Goodreads" that you can actually read - otherwise you're stuck with reading a paperback or other eBook (from either a Kindle or Nook) and update the pages accordingly.
