Zoo Station by David Downing

A few years ago my Grandfather started to speak of the war in bits and pieces. He sparked my interest in learning more. I've read several fictional books over the years about the war, but Zoo Station puts the icing on the cake.

What an intellectually fascinating written story of espionage, good and evil and the time leading up to the brink of war. As I got deeper into the story the more intrigued I became by the characters and their situation. This book touched my heart. A must read.
