It begins in an unnamed city nicknamed "the Fairest", it is distinguished by many things from the river fair to the mountains that split the municipality in half; its theaters and many museums; the Morgue Ship; and, like all cities, but maybe especially so, by its essential unmappability. Dora, a former domestic servant at the university has a secret desire--to find where her brother went after he died, believing that the answer lies within The Museum of Psykical Research, where he worked when Dora was a child. With the city amidst a revolutionary upheaval, where citizens like Robert Barnes, her lover and a student radical, are now in positions of authority, Dora contrives to gain the curatorship of the half-forgotten museum only to find it all but burnt to the ground, with the neighboring museums oddly untouched. Robert offers her one of these, The National Museum of the Worker. However, neither this museum, nor the street it is hidden away on, nor Dora herself, are what they at first appear to be. Set against the backdrop of a nation on the verge of collapse, Dora's search for the truth behind the mystery she's long concealed will unravel a monstrous conspiracy and bring her to the edge of worlds.
