Shipstead, who won the LA Times First Fiction prize for her bestselling debut, Seating Arrangements, writes with precision on both macro and micro levels, bringing a sure-footed fluency to descriptions of landscape, potted highlights of aviation history and close-up details of people and places (Prohibition-era prostitutes work out of basement apartments, “poking their heads up into the alleys like lascivious gophers”). She is interested in the way stories and lives alter through successive interpretations, like 'a game of telephone'

“We’re celebrated for marrying,” Marian writes to her twin brother, Jamie, “but after that we must cede all territory and answer to a new authority like a vanquished nation.” But both women, in their separate ways, are pursuing freedom in a male world that wants to confine them within preconceived ideas about who and what they should be. “I needed the relief of being someone who wasn’t afraid,” Hadley confesses. She is positioned as a counterpoint to Marian, whose pure and single-minded determination to fly contrasts sharply with Hadley’s tendency to drift through life with occasional bouts of self-sabotage. Hadley’s drily cynical voice has more than a touch of Fleabag about it, offering a knowing and prematurely jaded insider’s view of the movie industry (“my career is no longer a blow job-based barter economy,” she remarks).

Threaded through it is a parallel contemporary narrative, recounted by disgraced Hollywood starlet Hadley Baxter, who is trying to revive her career by playing Marian in a biopic.

Great Circle is a daringly ambitious novel, traversing in Marian’s story the history of early-20th-century aviation, Prohibition, the Great Depression and the second world war. “What I have done is foolish I had no choice but to do it,” she has written. Decades later, her enigmatic, fragmentary journal is discovered, wrapped in a life-preserver. The novel’s heroine, pioneering aviator Marian Graves, was attempting to become the first person to fly a great circle intersecting both poles in 1950 when her plane disappeared somewhere in the Antarctic.

The equator is one so is every line of longitude. A great circle, Maggie Shipstead’s third novel explains on the opening page, is “the largest circle that can be drawn on a sphere”.
