This is a great little story to tide me over until the next proper book. This us the story of Sarah and is a great parallel story to the main story arc
We see how the survivor are living day to day and the immense lack of facilities and utilities they must struggle with like their dorms which are just beds on crumbling floors blocked and dark passageways with missing floors and not to mention the fetid bathrooms!!!! Bleuuurgggghhhh!
We also see more of Gershom and his propaganda war against the Zmaj and his attempt to cut off supplies of water to the rest of the city!
