Inspired by the true story of the World War I American Women's Hospital, Mercy Road is a novel about love, courage, and a female ambulance driver who risks everything.

In 1917, after Arlene Favier's home burns to the ground, taking her father with it, she must find a way to support her mother and younger brother. If she doesn't succeed, they will all be impoverished. Job opportunities are scarce, but then a daring possibility arises: the American Women's Hospital needs ambulance drivers to join a trailblazing, all-female team of doctors and nurses bound for war-torn France.

On the front lines, Arlene and her fellow ambulance drivers work day and night to aid injured soldiers and civilians. In between dangerous ambulance runs, Arlene reunites with a childhood friend, Jimmy Tucker, now a soldier, who opens her heart like no one before. But she has also caught the attention of Felix Brohammer, a charismatic army captain who harbors a dark, treacherous secret.

To expose Brohammer means risking her family's future and the promise of love. Arlene must make a choice: stay in the safety of silence or take the greatest chance of her life.
