A wonderful, intriguing book that is based on true events from WWII. This book revolves around the true events of the German Enigma code, U-boats in the Atlantic, and the Bletchley Park cryptographers. This is, however, a fictional story with themes of romance and treason. I've heard this author compared to John LeCarre, so if you like his books, you may also enjoy this one.
