There's 'The Expats' by Chris Pavone. It has a female lead who is involved in a world of international intrigue and espionage. The story delves into her identity as a woman, a mother, and a spy, exploring how she balances these different aspects of her life while being involved in a dangerous game of secrets and lies. This novel gives a fresh perspective on the spy genre from a feminist angle.
One great feminist spy novel is 'The Spy Who Came in from the Cold' by John le Carré. Although written by a male author, it features strong female characters who subvert traditional gender roles in the spy world. Another is 'Red Sparrow' by Jason Matthews, which has a female protagonist who uses her wits and femininity as tools in the dangerous world of espionage. And 'A Woman of No Importance' by Sonia Purnell tells the remarkable true story of a female spy during World War II.
