"Violette and Virginia are two women whose stories needed to be told, particularly now that most of the people who fought in WWII are gone. Robuck has done their memory great honor." —BookPage (starred review)

"Following her triumph The Invisible Woman, Erika Robuck returns with an even more powerful book. Inspired by true stories, this incredible book tells of American Virginia and Violette, each swept up in the current of World War II and forced to choose whether to risk everything for the things in which she believes. Their lives collide in powerful and irrevocable ways that will hold readers spellbound… Sisters of Night and Fog stands head and shoulders above for its meticulous research, heart pounding storytelling, compelling relationships and important message. Bravo!" —Pam Jenoff, New York Times bestselling author of The Woman with the Blue Star

"A novel of duty, sacrifice, fate, and hope, set in a world steeped in courage and madness. Searing, powerful, and told through the lens of two overlooked historical figures who gave up nearly everything to fight against tyranny in one of the 20th century’s darkest hours, Erika Robuck's Sisters of Night and Fog soars. Two women—connected at the outset by fate, chance and little else—hurtle toward a tragic date with destiny in the infamous Ravensbruck Concentration Camp, where prisoners are starved and tortured, and not all will make it out alive. Based very closely on the true stories of two incredible 20th century women in the shadows, who risked their lives to save others, this novel, devastating in its truth and power, will break your heart and stay with you long after you’ve turned the final page." —Kristin Harmel, New York Times bestselling author of The Book of Lost Names and The Forest of Vanishing Stars
