This is an important and complex topic. Miller provides one of the only comprehensive looks at the intersection of story with digital technology available, dealing with interactive media of all sorts in a cogent and accurate fashion. It works as a textbook, which I would certainly assign to any introductory class. Plus, it's good, actually a wonderful read, even given its considerable length, due in large part to Miller's exhaustive research, masterful organizational coherence and elegant and clear writing style. Underlying it all, Miller has a clear voice that tells readers that she cares an awful lot about helping people understand this stuff, because she cares about it herself.
