I picked this up because I am a fan of Berg's other books, but I found this novel disappointing. It didn't add anything to my understanding of the war years (I have watched many movies from the 1940s), and without that setting as a novel framing device, the reader must rely on the interior life of the characters for the success of the novel. Unfortunately, the fact that the war is going on was pretty much the only interesting traits the characters had.
Honestly, watch Mrs. Miniver instead. (And The Miracle of Morgan's Creek for Tish's story!)
