I always use the IRC method for downloading books, you can usually get a book in every format.
>Download IRC client (I use Hexchat) and make sure its set up for receiving files
>Connect to IRCHighway for the server, the channel is 'ebooks'
>use the @search function to find your book. also works searching for an author. Search results will come in a .txt with full format etc information
>copy the entire entry for the download you want in the search results and paste it into the channel
