You don’t always get what you want in life, and no one knows that better than Lizzie Baker. Her only wish is to go home, but in order to do so, she has to find the one light on Brown Mountain that transported her back in time from 1969 to 1859.

When Lizzie’s one opportunity is thwarted, she remains trapped in the antebellum South, a time she’s come to loathe, but that’s not the only reason she’s anxious to return home. The Civil War looms ever closer and she is frantic to leave before the deadliest and bloodiest conflict in American history descends on Brown Mountain.

Lizzie spends her days helping the Collins sisters doctor the people on Brown Mountain and in the little town of Morganton, North Carolina. While learning about the natural healing methods the sisters use, she teaches them the more modern medicine she learned in medical school.

But it’s the nights that keep Lizzie going, searching the mountain with her best friend Abbie to find the one light that can take her home and engaging in secret meetings with Josh Hampton, a plantation owner’s son, risking her life as she helps him lead slaves to freedom.

As time goes by, Lizzie begins to care deeply for Josh, enough that she questions what she will do if the opportunity to go back to her time ever presents itself. Will she step into the light or will she choose to stay with Josh? She fears that when the time comes, she will only have a split second to make that decision and can only pray it will be the right one.
