I'd stay far, far, far away if I were you. It's registered to someone with a phony email address (first warning), it offers books that are not in the public domain for free (second warning), and when you click to download, it downloads an .exe file (third warning!). I didn't actually download the .exe file to see what it was, but I imagine it installs a virus or spyware on your computer. There's no reason to package an ebook file inside an .exe, and never, ever download an .exe unless you know exactly what you're getting!
