George and Edie are travelling through unLondon, a world of danger on the city streets, and they are quite alone. Time is standing still, and the rest of London is unaware of their plight, unaware of the hidden world of living statues, of Shackleton and the Queen of Time.

In the concluding part of the breathtaking and critically acclaimed Stoneheart trilogy, Edie and George look deeper into Edie's past, and her future.
