Query: Stayed with me for 20 years

I read this book when I was around 10 or 11. I'm 32 now and I always find myself going back to this book. I highly recommend it to teachers and students studying World War II. I learned and felt so much while reading this book. On my many trips to Europe I have skipped Vienna because I'm saving it for a trip when I can spend an extended period of time and reread the book. Highly recommend.
