In the book Refugee by Alan Gratz, I think that the author chose to write about all three of these stories because they all relate. They relate one way because all of the characters are facing violence in their home town. Also, Mahmoud, who lives in Syria in 2015, needs to flee to Germany, and Josef lives in Germany in the 1930’s, but needs to flee to Cuba, and Isabel lives in Cuba in 1994. I think that the author also chose to alternate each story every chapter because it makes it easier to relate all of the stories.

This book is an amazing historical fiction book.
