In August 1933, the famous aviatrix Grace O'Gorman recruits the inexperienced Willa Briggs to accompany her in breaking the world flight endurance record. While circling Toronto, the women must deal with fatigue, the weather, and the sabotaging efforts of Grace's husband. Meanwhile, on the ground, anti-Semitism erupts and affects some of those connected with the women. Unable to communicate with words in the sky, Grace and Willa find new ways of communicating that change their views of the world, and Willa, with this new awareness, finds her feelings for Grace becoming more complicated. "Leaving Earth" is a magical and adventurous story, based on some true events, about women challenging the often-stifling roles of the 1930s. The book glimmers and comes alive, showcasing Humphrey's lush style in her first novel.
