I am not sure if the link is right but I found a link that matches the name of the ebook you need:
http://bit.ly/2dozT0W (I don't know why it's a .exe file. I may contain the PDF too but I am not so sure about it)
lol you're too naive for the internet.Surprise,it's a virus or another malware sure to slow down his system.After installing .exe,you will see various types of extensions and what not automatically installed on your system.Give it a try.
I told him that it's an exe file and can understand the fact that it may contain a virus too but my antivirus did not detect any such thing. I'm aware of the phishing links but any link could be a malware. I just posted it here incase he wants to see if it contains the ebook.
These links have already been posted and they don't contain the ebook link.
