Critically acclaimed author of The Ashes Trilogy, Ilsa J. Bick takes her new Dark Passages series to an alternative Victorian London where Emma Lindsay continues to wade through blurred realities now that she has lost everything: her way, her reality, her friends. In this London, Emma will find alternative versions of her friends from the White Space and even Arthur Conan Doyle.

Emma Lindsay has nowhere to go. Her friends are dead. Eric and Casey are lost to the Dark Passages. Emma commands the cynosure, a device that allows for safe passage between the Many Worlds, to put her where she might find her friends again. But Emma wakes up in the body of Little Lizzie, all grown up. And in this alternative Victorian London, Elizabeth McDermott is mad.

Elizabeth's physician, Dr. Kramer, has drugged her to allow Emma—who's blinked to this London before—to emerge as the dominant personality.

Elizabeth is dying, and if Emma can't find a way out, everyone as they exist in this London will die with her.
