Can anybody tell me how does Turks got into this book in the year 1096? It is a shame that after citing all these history books they will sit and write a book without a factual check.For those who have no idea what I am talking about: Turks got into Asia Minor (Anatolia) in the year 1071 and they were no where near the first Crusaders. They might have been in the Muslim armies fighting against the Crusaders but calling the Muslims "Turks" is a grave error for these authors who claim to write according to historical facts.I am great fan of historical novels but this book definitely doesn't fall into that category.
