As with any WWII story involving a Jewish person living in Germany, it's bound to be sad. I felt connected to the characters, but the author's style really made this a tough read. The story was set up like a documentary, only in book form. There would be bits of prose, excerpts of diaries and letters and then straight dialogues from interviews. These elements were not synthesized in a way that made reading it enjoyable.
This is a story of a young German mother who meets a Jewish woman and begins to house her. They fall in love rather quickly, since Elisabeth (or Lilly, or Aimée) was unhappy in her marriage to a Nazi soldier. Felice (or Jaguar), the illegal Jew, lives happily with her lover until, of course, she is captured by the Gestapo. The struggles that follow, and Lilly's brave attempts to help Felice make up the bulk of the story. Reading about the lives of Jews in Nazi-era Berlin was of course depressing, but the most chilling part of this read came at the very end, where the author describes the living conditions of a hopeless, possibly deranged Lilly in her old age.
Perhaps a WWII enthusiast would better enjoy this book, but again the writing style just didn't do it for me.
