Well, the entire book (784 pages to be precise) are all available online for Free download in the form of Photos (very messy) as well as a few sites offering pdf formats.
The sites are offering Torrent downloads and the few that offered direct download of Harry Potter and the Deathly Hallows on Rapidshare and Megaupload have been blocked in No time - Just shows how serious the publishers and JK Rowling are with this release.
I wouldn't put up the links of the sites were the book is available for Free download due to Copyright and Privacy Infringement Issues. But I can give you the exact phrase that you need to put in google to reach the torrent files. "Harry Potter and the Deathly Hallows filetype:torrent" << Use the phrase inside the quotes to catch the fish!!
I am NO fan of Harry Potter - So I will wait for reviews from you guys on how the so called Last series is. Do drop in your comments below.
