"The Politically Incorrect Guide to Islam and the Crusades" by Robert Spencer is the book you're looking for. I would recommend anything by him on the subject of Islam and Muslims. Spencer does not engage is apologetics for Islam and puts the blame squarely on them for their violent history of conquest.
Additionally, I strongly recommend "The Myth of the Andalusian Paradise" by Dario Fernandez-Morera, which uses original sources to show that life as a White person under Islamic rule was miserable, and that jews got special, preferred treatment, as they always do.
