Great Circle by Maggie Shipstead is a decades-spanning tale of a trailblazing woman pilot and the modern-day actress who is preparing to play her in a Hollywood blockbuster. Marian devotes her entire life to becoming the best possible pilot she can be, but her attempt to circumnavigate the North and South Poles ends in tragedy. A century later, Hadley Baxter immerses herself in Marian's story in preparation for the role of a lifetime only to discover she has more in common with Marian than she could have ever imagined.
