What is good book on the Crusades?

My apologies if this is the incorrect forum. I would like to educate myself on the Crusades, but it seems there are literally hundreds of books on the subject. I’m guessing the majority of them are bias and have an agenda. I am looking for something historically factual or viewed through Catholic’s point of view.

Thank you.
