In 1910 London, independent-minded Katharine Hilbery defies her family's expectations of marriage to pursue a career in astronomy. But when her father pressures her into an unwanted engagement, her resolve is tested. Through new friendships—including a bold suffragette and a thoughtful editor—Katharine begins to question the limits placed on her by society, love, and tradition, ultimately searching for a path that is truly her own.
