The Diamond Eye is a work of historical fiction published in 2022 by Kate Quinn. The novel’s main subject is the World War II experiences of Soviet sniper Lyudmila Pavlichenko and her turn from soldier to cultural representative as she journeyed to the United States and befriended First Lady Eleanor Roosevelt. The work is largely based on Pavlichenko’s memoir, and Quinn includes extensive further reading in the work’s back matter. Much of Quinn’s subsequent work concentrates on the roles of women in war, including The Alice Network (2017), The Huntress (2019), and The Rose Code (2021), several of which have been New York Times and USA Today bestsellers.
