At the Heart of the White Rose: Letters and Diaries of Hans and Sophie Scholl
Hans and Sophie Scholl were young Germans, executed by the Nazi's during WWII for their resistance efforts as part of the White Rose. I don't remember how I found out about these two, but I became fascinated and wanted to learn more. I'm finally getting around to it.
Entirely comprised of the personal correspondence of Hans and Sophie, thus far this book is a bit like The Diary of Anne Frank. I like to think that I have a decent grasp of the English language, but these two, Hans in particular, put me to shame. The eloquence in their writing, the personal thoughts and feelings they reveal to friends and family, surpass the emotion I'm willing to share with my diary, let alone another human being. It's amazing, inspiring and a little sad.
