At the Spire, a sprawling mountain of metal and stone in the middle of a radioactive desert, Shå, the Commander of the City Watch, is tasked with keeping the hodgepodge of forgotten technology and new biology safe. When a string of grisly murders is committed just as a new Baroness of the Spire is about to be sworn in, Shå will have to find the killer and bring them to justice.
