The Nightshade - Hattie James 4 - Stacy Lynn Miller - English

December 1941: As bombs fall on Pearl Harbor, singer Hattie James faces a personal nightmare when her sister Olivia vanishes. The kidnappers demand an impossible price—her father's classified list of undercover American and Nazi spies.
Wartime paranoia and family loyalty take Hattie to Washington D.C. with Maya and Commander Leo Bell to hunt an elusive, high-ranking mole in the War Department who is after those lists. Leo, a military intelligence officer with access to classified operations, becomes their crucial inside man, navigating the treacherous corridors of power. Meanwhile in Rio de Janeiro, Hattie’s father Karl slowly recovers from near-fatal wounds under her mother's watchful care as Nazi agents close in on his location.
As war declarations echo across radio waves, these fragile alliances become Hattie's only hope of untangling a conspiracy that threatens both nations. As Hattie inches closer to the truth, she discovers that exposing the traitor might save her sister—or destroy them both.
