Two sisters. One unassuming haven. Endless opportunities for grace.

Sisters Margaret and Evelyn Justice have grown up in the prosperous Greenwood District of Tulsa, Oklahoma--also known as Black Wall Street. In Greenwood, the Justice sisters had it all--movie theaters and entertainment venues, beauty shops and clothing stores, high-profile businesses like law offices, medical clinics, and banks. While Evelyn aspires to head off to the East Coast to study fashion design, recent college grad Margaret plans to settle in Greenwood, teaching at the local high school and eventually raising a family.

Then the 1921 Tulsa Race Massacre upends everything they know and brings them unspeakable loss. Left with nothing but each other, the sisters flee along what would eventually become iconic Route 66 and stumble upon the Threatt Filling Station, a safe haven and the only place where they can find a shred of hope in oppressive Jim Crow America. At the filling station, they are able to process their pain, fill up their souls, and find strength as they wrestle with a faith in God that has left them feeling abandoned.

But they eventually realize that they can't hide out at the filling station when Greenwood needs to be rebuilt. The search for their father and their former life may not give them easy answers, but it can propel them--and their community--to a place where their voices are stronger . . . strong enough to build a future that honors the legacy of those who were lost.
