Query: Excellently structured

What impresses me about this book (apart from the wonderful ideas that permeate the entire UA line) is the very clear structure to the extended story within.The story occurs in a series of discreet episodes. The order of these is set, regardless of what players might do, but that doesn't matter - within each episode is considerable freedom of movement. In each, the players' decisions will promote one or another of various powerful characters and at the end they will have been instrumental in changing the world.I found the book very easy to read and follow, well-structured, and a useful example of how to construct such an extended story.
