This is a novel of alternate history set in a divided England. The land is divided, following the Luddite revolution, into the puritan, progress-hating north and the decadent, Royalist south. Living right on the border and flitting between the two nations Elizabeth Barnabus lives a precarious double life - as both herself and posing as her own brother, the daring private detective. Now she is trying to solve the mystery of a disappearing aristocrat and a hoard of arcane machines.
