"After being rescued as infants from a sinking ocean liner in 1914, Marian and Jamie Graves are raised by their dissolute uncle in Montana. There--after encountering a pair of barnstorming pilots passing through town in beat-up biplanes--Marian commences a lifelong love affair with flight. At fourteen she drops out of school and finds an unexpected patron in a wealthy bootlegger, an arrangement that will haunt her for the rest of her life, even as it allows her to fulfill her destiny: circumnavigating the globe by flying over the North and South Poles. A century later, Hadley Baxter is cast to play Marian in a film centered on her disappearance in Antarctica. Scandal-plagued and trapped in her role as a Hollywood wild child, Hadley is eager to redefine herself after getting fired from a romantic film franchise. Her immersion into the character of Marian unfolds alongside Marian's own story, as the two women's destinies--and their hunger for self-determination in vastly different places and times--collide. Epic and emotional, meticulously researched and gloriously told, Great Circle is an astounding feat of storytelling and an exhilarating tour de force."--Back cover.
