Peggy Devona can communicate with ghosts in 1897. Because she is fearful of the things the dead might reveal through her, she hides her talent from those who are afraid of a girl with such abilities. Peggy understands that her best friend can only be saved by her - a whisperling - when she is charged with killing her wealthy mistress. Peggy makes her way to her uncle's psychic shop in the city where she searches for fresh spirits to assist her in solving Sally's case. However, time is running short, and each move Sally makes to learn the truth also moves her closer to the death penalty.
