Books on the DDR

[Diello]

I'm interested in reading a book on the history of the German Democratic Republic. (Failing that, I'd also like a book that documents East German society and politics in some generalized way; anything other than a purely personal narrative.)

This board has always supplied me with excellent recommendations.

Crossing the River by Victor Grossman. very good book on the DDR, the Cold War, and the Eastern Bloc in general.
