In the fall of 1895, Etta Place falls in love with Harry Longabaugh, alias the Sundance Kid. She gives up everything to follow him and his partner-in-crime, Butch Cassidy, in their outlaw life across the continent and beyond. Breathtakingly beautiful and every inch a lady, Etta can also ride and shoot as well as any man. As their fugitive life begins to crumble, she finds herself alone and living in a convent with her newborn son. Knowing she can't hide away forever, she moves halfway across the country to begin anew. Etta prays her past won't catch up with her.

In 1911 Emily Pleasants steps onto the train station platform of Pine Creek, Minnesota with a teacher's contract in hand and a secret life she's fled. A young widow with a small son, she's searching for a safe place to raise her child where no one will recognize her. She meets Edward Sheridan, a successful merchant and bank owner, who quickly falls for her beauty, intelligence, and kindness. Still, she worries her notorious past will threaten the one thing dearest to her-her son.

From the deserts of Texas to the sweeping vistas of Wyoming, the refinement of New York City to the lush valleys of Argentina, Etta followed the outlaw men she loved so dearly. And then, she disappeared.

One woman, two separate lives. What became of the elusive Etta Place?
