I've never used this site before. It didn't set off any alarms with my antivirus software, but you never know. Anyway, I searched Google for a particular book, and saw this site in the results. It appears to just let you download ebooks. I tried Christopher Paolini's Inheritance, and even though there's a login page, I didn't have to log in.
After going to the site, I clicked on the Paolini book, which brought up another page. On that second page, I right-clicked "Download for iPad/iPhone", and did a Save As, and the book is on my PC now. I double-checked, and the entire book is there.
I performed a few more searches in an attempt to see how fully-featured the site was. I found lots of Stephen King, lots of Hunger Games, but I didn't find any Salman Rushdie.
One more time, I hadn't seen this site before today, and I cannot vouch for it, but at least right this minute, it's permitting me to download ebooks with no login. It may be run by Russian hackers, or by the NSA, or by some book enthusiast--I just don't know. Good luck.
