Bonhoeffer

I must admit I am not far along in the book.  According to Kindle 10%.  What a great historical reference.  Makes many things about WWII much clearer and that is only in the first 10%.  This should be a great one to discuss just from the things that we will learn.   The study of Bonhoeffer's character and characteristics will be compelling as well.  I wonder what I will learn about the plot to assassinate Hitler as well.  Has anyone else gotten further in the book?  What do you think?
