Along the Infinite Sea by Beatriz Williams

This is apparently one in a series of books about the Schuyler sisters (not the Hamilton ones).  I am guessing they are all of the light beach read variety but this one has a WWll connection which, I imagine, is why it landed in my reading stack.  Pepper Schuyler is a socialite member of the 1966 Washington D.C. political scene who finds herself pregnant and unwilling to identify the father and therefore out of a job.  To raise money she decides to sell an old Mercedes that has been stored in a family shed.  The buyer is an intriguing woman named Annabelle.  It turns out that this car once belonged to Annabelle and it is her story that makes the novel interesting.  In the 1930's Annabelle was living in France in love with the charming Stefan.  Then he disappeared in the Nazi sweep of European Jews.  Hoping to save Stefan and others, Annabelle married the German General von Kleist.  At different points each of the characters must make a moral choice.  Something or someone will be saved and as a result something or someone will be lost.  Not a Pulitzer contender but a satisfying read anyway.
