Sacramento, 1885. Edie et Violet Bond, soeurs jumelles de dix-sept ans, sont de puissantes médiums : Violet sait ouvrir le Voile qui sépare la vie de la mort, et Edie est capable de le traverser pour arpenter le monde des esprits. Mais leurs dons ne leur ont été d'aucune aide quand, suite à la mort de leur mère, leur père a menacé de les faire interner dans un asile. Après avoir fugué, Edie et Violet ont rejoint une communauté soudée de femmes - poétesses, actrices, musiciennes et oratrices, sous couvert de communion avec les esprits, elles peuvent se permettre de dire en public ce qui leur est normalement interdit.

Sacramento, 1885. Edie and Violet Bond know the truth about death. The seventeen-year-old twins are powerful mediums, just like their mother--Violet can open the veil between life and death, and Edie can cross into the spirit world. But their abilities couldn't save them when their mother died and their father threatened to commit them to a notorious asylum. Now runaways, Edie and Violet are part of a traveling Spiritualist show, a tight-knit group of young women who demonstrate their real talents under the guise of communing with spirits. Each night, actresses, poets, musicians, and orators all make contact with spirits who happen to have something to say. . . notions that young ladies could never openly express.
