Along the Infinite Sea by Beatriz Williams

Each of the three Schuyler sisters has her own world-class problems, but in the autumn of 1966, Pepper Schuyler's problems are in a class of their own. When Pepper fixes up a beautiful and rare vintage Mercedes and sells it at auction, she thinks she's finally found a way to take care of herself and the baby she carries, the result of an affair with a married, legendary politician.

But the car's new owner turns out to have secrets of her own, and as the glamorous and mysterious Annabelle Dommerich takes pregnant Pepper under her wing, the startling provenance of this car comes to light: a Nazi husband, a Jewish lover, a flight from Europe, and a love so profound it transcends decades. As the many threads of Annabelle's life from World War II stretch out to entangle Pepper in 1960s America, and the father of her unborn baby tracks her down to a remote town in coastal Georgia, the two women must come together to face down the shadows of their complicated pasts.

Indomitable heroines, a dazzling world of secrets, champagne at the Paris Ritz, and a sweeping love story for the ages, in New York Times bestselling author Beatriz William's final book about the Schuyler sisters.
