Modern day kids Annie and Nico go on a magical history tour back to the Middle Ages to find out what started the Crusades - and why there were so many of them. They travel to Jerusalem (where it all started) and they meet kings and popes and emperors and sultans... including Richard the Lionheart and his famous adversary Saladin. Along the way, Nico discovers that the Crusades weren't just about religion and the Holy Wars weren't just between Christians and Muslims. Experience the ins and outs of this confusing time with Annie and Nico as the helpful guides in this pocket-sized book.
