** spoiler alert ** 
 This book was definitely one of my favorite historical fiction books ever. I have read a few of Elizabeth Wein's books like Rose Under Fire and I really liked it as well. This one was exceptional. I loved both Teo and Emmy. When I first started reading this book, I was drawn into it. In the middle was going pretty slow and it was kind of a hard book to read. But as I as I got up to the part where Teo and Em were learning how to fly an airplane, it started to get really interesting. I love the brother sister relationship between Teo and Em. They knew each other so well and were always there for each other throughout the whole book. The author herself also mentioned that it was very hard for her to write this book. The time period takes place at the very beginning of World War II, when America was still neutral. Instead of writing about Americas point of view it showed the war between Italy and Ethiopia. I think the author chose to write about this war because many people aren't much informed about this war. Its kind of like a forgotten war. Some of the things about the war were quite confusing since I never heard about the war between Ethiopia and Italy. The ending of this book was very bittersweet which I actually prefer over a happy ending. Teo and Emmy now lived in America, but they had to leave their Momma behind which is very sad an hard for them. Also, since Teo is adopted, he isn't legally Rhoda's child anymore. But like he wrote he is still her Teo. This book is definitely one of my favorites and I recommend to all teenagers.
