What an interesting aspect of WWII research. This historical novel looked at the war through the lens of music and its influence on entire cultures and nations. Not just any music, but that of the famous Soviet composer Dmitri Shostakovich, peering into his entire tumultuous, revolutionary life in Leningrad and seeing the common "chord" through it all that never lost Shostakovich’s focus. A passionate story that bolsters music as one of the all-time unifiers in life.
