Query: The innocent?? More like the ridiculous!

I really wanted to like this book. It's set in Berlin, cold war, all the things that interest me. This book never gets me to believe anything about the main character. He's incompetent at best. Time spent describing cardboard boxes is tedious, and we never get any detail about the actual tunnel or the spy element to this whole story. To say this book lacks suspense is a bit of an understatement. The whole story is preposterous....young man, unsure of himself, falls for first girl he sees....I thought a high school kid wrote this book. The author thinks that by dropping in a name of a famous street here and there, it is enough to place you in Berlin. It's not. Save the $15 and buy something else.
