The Tides of Time by Sarah M. Eden

In 1793, a storm propels Lili forward through time, kindling a love that transcends the ages.

Fleeing the clutches of Robespierre’s revolutionary Tribunal in France, Lili Minet makes a desperate escape on a ship headed to England, but her dangerous flight takes an unexpected turn when a violent storm catapults her off the ship and eighty years into the future, leaving her stranded in the unfamiliar world of 1873 England.
When lighthouse keeper Armitage Pierce rescues a woman from the tumultuous sea, he does not anticipate her silent, cold response to his gallant efforts. Though he is wary of this woman and her odd behaviors, he finds she is just as wary of him. And he can sense that she is not telling him something of great import to her. Only Armitage’s grandfather, a man seasoned by the mysteries of the sea, can seem to penetrate Lili’s defenses to offer her support. But as Lili heals from the physical and emotional wounds of her ordeal and Armitage continues to offer light and safety to her, a tender friendship blossoms between the two.
Yet the shadow of danger looms as the threat that chased Lili from France all those years ago reemerges in her new present. Together Lili and Armitage must navigate the challenges of a love that defies the boundaries of time and the perils that reach across the decades to ensnare Lili. As the storm clouds gather, Lili and Armitage face the ultimate test—whether their bond is strong enough to rewrite the pages of history itself to save them and their love.
