In 1912 aboard the RMS Titanic, Nabiha “Bea” Nohra is traveling to America to find work, eager to earn the funds necessary to afford passage for the family she left in Lebanon. On the same ship, heiress Marguerite Ashby sails home to celebrate her engagement to a dull British lord, a marriage that will secure her new-money family’s place in old New York society. But when the Titanic sinks, the two women’s paths are fused together when Bea saves Marguerite’s life and they are unexpectedly charged with the smallest survivor—a baby boy.

No one claims the infant, so the women form a committee to aid survivors and locate the baby’s next of kin. Bea works as the child’s nanny, desperate to bring her family to America before the difficulties in Lebanon overwhelm them. Meanwhile Marguerite hopes the committee’s charitable efforts will win society’s respect and render an advantageous marriage unnecessary, sparing her from marrying a man she does not love—unless her parents force her to fulfill the obligation no matter what society says. And when finding the child’s relatives proves to be no simple task, the women are soon enmeshed in deception and uncertainty as they seek to determine where the baby truly belongs.

The committee might grant the acceptance Marguerite craves, connect Bea with the stability she needs, and lead them to the baby’s relatives. But a committee helmed by an American heiress and a Lebanese nanny is hardly customary. Surviving a shipwreck is only the start. As Marguerite’s wedding looms nearer and Bea faces the increasing hardships of adjusting to her new country, they must fight for survival once more. This time, to survive New York society.
