The Cure for Dreaming by Cat Winters

A "spellbinding" tale of a headstrong young woman, a mysterious hypnotist, and a battle for freedom in early twentieth-century Oregon (School Library Journal).
Olivia Mead is a headstrong, independent young suffragist in an age that prefers its girls to be docile. It's 1900 in Oregon, and Olivia's father, concerned that she's headed for trouble, convinces a stage mesmerist to try to hypnotize the rebellion out of her. But the hypnotist, an intriguing man named Henri Reverie, gives her a terrible gift instead: she's able to see people's true natures, manifesting as visions of darkness and goodness, while also unable to speak her true thoughts out loud.
These supernatural challenges only make Olivia more determined to speak her mind, and so she's drawn into a dangerous relationship with the hypnotist and his mysterious motives, all while secretly fighting for the rights of women. Cat Winters, award-winning author of The Uninvited, breathes new life into history once again with an atmospheric, vividly real story, including archival photos and art from the period throughout.
