For 500 years, the once powerful order of the Sibylline has kept the identity of its future prophetess hidden in the most famous painting in the world. Amid the chaos of post-World War II France, one woman discovers their ancient secret and its ability to transform a fragmented world.

After 480 days as a Nazi political prisoner, Dr. Marie Guerrant returns to Paris to repatriate the Mona Lisa and find her daughter. When a British Colonel arrives claiming he needs her French Resistance connections to find the lost painting, which she helped hide seven years earlier, distrust is high. Tipped off about her daughter's involvement and the Colonel's obsessive belief that the Mona Lisa contains the identity of a modern-day Sibyl prophetess, Marie must risk her life to save her daughter and the masterpiece from men consumed by controlling destiny.

On the eve of rising as the Sibyl of Amboise, Aesmeh de la Rose must rely on her visions to find Leonardo da Vinci after he and the Mona Lisa disappear from his workshop at Clos Lucé. The precious painting and its creator cannot be lost or the ancient Sibylline Order faces extermination after more than 1000 years of rebuilding their powerful matriarchy. Torn between duty and love, Aesmeh must tap into an ancient alchemy in a race to keep the Order safe. But, an unspeakable betrayal forces her to make an unfathomable choice to secure the future of the Sibylline.

This rich alternate history binds two women beyond time, each fighting to restore sight to a world blinded by the power and control of men. The fate of the world rests on their courage to reclaim the ancient feminine powers of the Sibylline. Woman on the Wall is a sweeping fantastical tale of intrigue and hope for us all.
