"From the New York Times bestselling author of the Maggie Hope series comes a tantalizing standalone novel about a mother and daughter who stumble upon an underground Nazi cell in Los Angeles during the early days of World War II--and find the courage to go undercover. June 1940. France has fallen to the Nazis, Britain is next--but to many Americans, the war is still something happening "over there." Veronica Grace has just graduated from college; she and her mother, Violet, the widow of a Navy commander, are looking for a fresh start in Los Angeles, where the sun always shines and the opportunities feel riper. Having taken a misstep that cost her a prestigious career opportunity back in New York, Veronica is relieved to take a temporary typing job--only to realize that she's working for one of L.A.'s most vicious anti-Semitic propagandists. Overnight, Veronica is exposed to the dark underbelly of the place she now calls home, where German Nazis are recruiting new American members and building a bunker in the Pacific Palisades for Hitler's anticipated visit to the West Coast. After the FBI dismisses their concerns for "lack of evidence," Veronica and Violet decide to call on an old friend of Violet's late husband--who introduces them to Ari Lewis, L.A.'s anti-Nazi spymaster. At once, the two blonde-haired, blue-eyed German American women go undercover and infiltrate the heart of Nazism in Los Angeles. Risking their lives, Veronica and Violet aim to gather enough information about the California Reich to take to the authorities. But as the news of the attack on Pearl Harbor ripples through the Nazi population in Southern California, and President Roosevelt declares war, the Grace women realize that the plots they're investigating are far more sinister than they feared--and even a single misstep could cost them everything. Inspired by real events, Mother Daughter Traitor Spy is a powerful portrait of family, duty, and deception that raises timeless questions about America--and what it means to have courage in the face of terror"--
