It's free if you have kindle unlimited. IIRC, 3-4 bucks if you don't.
There are a number of websites and other sources of information about the true nature of Islam. It is much worse than Nazism, Fascism, or even Communism, as you will discover once you do your own research. Most people, 99%, don't know its true nature, history, goals, and etc. That's why its followers get away with what they do.
I see someone sent you a link to a very good video about its history. I highly recommend it as well - it's only about 45 minutes long and will give you a really good start to understanding its history and goals.
Dr. Bill Warner's website, the person who gave the siminar in the video you were linked to: http://www.politicalislam.com/. Much good information on his site.
Standing by, ready to assist in furthering dissemination of the truth about Islam and in opposition to the billions spent promoting it.
God bless.
