In 1929, twenty daredevil women take to the skies in the most dangerous race of their lives.

Florence “Pancho” Barnes—heiress, rebel, and the most colorful pilot in America—can outfly, outswear, and outdrive any man. When Hollywood tries to turn the first-ever cross-country National Women’s Air Derby into a publicity stunt with movie starlets and their male “mechanics” doing the real flying, Pancho rallies the greatest female aviators of the era to fight back.

Alongside aviation legends Amelia Earhart, Louise Thaden, and Marvel Crosson, these fearless women demand the right to fly solo across 2,800 miles of treacherous terrain in primitive, fragile aircraft held together by glue and prayers. But as the race begins, sabotage strikes. Someone wants these women to fail—or worse.

As increasingly serious incidents mount, the pilots realize they’re not just racing for glory. They’re fighting for their lives and the future of women in aviation. United in their determination to finish the derby, they refuse to back down, watching each other’s backs as they barrel across the country in a white-knuckle race that will determine once and for all whether women belong in the skies.

From high-speed car chases to emergency landings, speakeasy showdowns to courtroom battles, Where the Sky Begins is a thrilling ride through one of aviation’s most dramatic chapters—a story of courage, sisterhood, and the unbreakable spirit of women who refused to be grounded.
