"In some ways Scrivener's Moon is going to be a return to the scale and scope of the first four Mortal Engines books; there's an epic journey, a large cast of characters, and several interweaving storylines. There is a bit about the Scriven, a bit about the Sixty Minute War, and a lot about the nomad empires and the construction of the new London."
