comment on structure

The book is divided into four Parts or chapters. Each Part is titled, but within each Part there are only blank spaces to denote a change of scene and the occasional blank page to denote a major break in the story within a named Part. There is no table of contents, but at the beginning of the book there are two lists, one of characters and one of place names. The place name list differentiates between fictional names and those which refer to existing places in modern day Britain. These are followed by a critically important map of the Kingdoms of Britain in 525 AD.
