April, 1912: It's the perfect finale to a Grand Tour of Europe—sailing home on the largest, most luxurious ocean liner ever built. For the Fortune sisters, the voyage offers a chance to reflect on the treasures of the past they've seen and contemplate the futures that await them.

For Alice, there's foreboding mixed with her excitement. A fortune teller in Egypt gave her a dire warning about traveling at sea. And the freedom she has enjoyed on her travels contrasts with her fiance's plans for her return—a cossetted existence she's no longer sure she wants.

Flora is returning to a fiance, a well-to-do banker of whom her parents heartily approve. Another man—charming, exasperating, completely unsuitable—occupies her thoughts, daring her to follow her desires.

Youngest sister Mabel knows her parents arranged this Grand Tour to separate her from a jazz musician. But Mabel has little interest in marrying at all, preferring to explore ideas of suffrage and reform—even if it forces a rift with her family.

Each sister grapples with the choices before her as the grand vessel glides through the Atlantic waters. Until, on an infamous night, fate intervenes, forever altering their lives . . .
