Reading letters written to her grandmother decades before, Cara Serafini finally learns the great secret, the triumph, of Giulia's life—the love she shared with her first husband, Paolo.

It's a love that began when Giulia left the Italian village of her birth and came to New York, where Paolo Serafini captured her heart…and took her dancing on Sunday afternoons.

And as Cara discovers, it's a love that's never ended—and never will.
