Along the Infinite Sea by Beatriz Williams

In this final book of the Schuyler Sisters trilogy, it's 1966 and Pepper is in Florida, having just sold a vintage Mercedes to Annabelle Dommerich. The sale, Pepper hopes, will give her the financial freedom to have her baby on her own, and leave behind her former lover--a senator. She is trying to keep a low profile, so he can't find her. Pepper is intrigued by Annabelle and why she would pay so much money for a car. Annabelle, in turn, finds that Pepper reminds her of her younger self, back in 1930's France. At the time, Annabelle fell hard for Stefan, but all of Europe was beginning to destabilize with Hitler's rise to power. With Stefan being a German Jew, the outlook for their relationship was even more dire. Along the Infinite Sea recounts the storylines of Pepper and Annabelle in alternating chapters. A satisfying end to the trilogy.
