At the turn of the twentieth century, Spiritualism and séances are all the rage—even in the scholarly town of Cambridge, England. While mediums dupe the grief-stricken, a group of local fringe scientists seeks to bridge the gap to the spirit world by investigating the dark corners of the human mind.
Each running from a shadowed past, Kate, Asher, and Elsie take refuge within the walls of Summerfield College. But their peace is soon shattered by the discovery of a dead body nearby. Is this the work of a flesh-and-blood villain, or is something otherworldly at play? This unlikely trio must illuminate what the scientists have not, and open a window to secrets taken to the grave—or risk joining the spirit world themselves.
