"I can't leave you, Mama. I can't go," Lily sobbed. "Then don't say goodbye," Chloe whispered, pressing the cherished family heirloom into her daughter's palm. "Just say: until we meet again."

Paris, 1923. Lily Levin boards a train with her baby daughter Mimi and American husband, leaving behind her beloved mother Chloe for a new life across the ocean. Carrying her mother's precious diamond pin and the Yiddish lullabies she sings to Mimi, Lily faces an uncertain future in a country she's never seen.

In New York, as Lily struggles to fit in, she finds an unexpected ally in Gloria, a young mother hired to care for Mimi. The two women forge a friendship deeper than blood as they share dreams, fears, and their fierce love for their children. 

Then tragedy shatters their world. One brave mother must make an impossible choice that sends her and two children on a voyage—to a Europe where Hitler's Nazi Party is gaining power and darkness is rising.

A heart-wrenching and powerful story of love, sacrifice, and finding strength in the most desperate of times, from USA Today bestselling author Roberta Kagan.
