Combined over 6.4 million people died in the Holocaust, Syrian War, And the Crisis in Cuba and thousands of Refugees fleeing to other countries trying to get their freedom according to the New York Times. Alan Gratz showed the ways people were treated and felt in all of these huge situations in history in this book combining 3 fictional characters and showing their journeys just how it happened in real life. All the characters in this story were fleeing their country Germany, Cuba, and Syria and they left for good reasons, saving themselves from extreme danger. Josef, Muhammed, and Isabel were all children when really bad stuff happened in their country making them flee to countries letting them in. Many people tried to hurt them and people like them in their era Fidel Castro, Cuban Police, Adolf Hitler, Nazis,Aleppo so many people just tried to hurt them and make them scared. Just a explanation on how bad it was Muhammads apartment got exploded, Someone's father got beat up by police it was terrible. Refugee was really cool. It had real events with fictional characters and people who like history with a little bit of fiction that were about 12 and up would love this book.
