Abylin and Scarlet will take a case where the bridge between the world of science and that of the imaginative mind unfolds.
Abylin Howell and Scarlet West live in 1890 London, hunting the unrighteous to the crawlspaces of the city. A link closer than the bond that joins sisters is about to be broken. With the arrival of a sketchy thief, a curious client, a missing girl who is the key to the mystery, and at least 12 murders, a new crime thriller unfolds. Scarlet and Abilyn must search for the killer in this world and the world of the mind and will be swept up into a plot that runs deeper and darker than they could have ever imagined.
