Code Name Verity by Elizabeth Wein

Set during WWII two very different young women become unlikely best friends. One is a pilot and one is spy. When a mission to France goes wrong the spy is captured by the Gestapo and the story begins with her written 'confession' to her captors.

I loved it. It was brilliant. It was beautifully written and emotionally moving. The characters were wonderful and the friendship between the two girls was amazing. I loved them. The structure of the book was unusual but it ended up working really well. It was also ( emotional reaction )

I would definitely highly recommend this book with a note that I think it would be best read with no previous knowledge about it. Don't even read the blurb on the book.
