 The author has left a number of threads trailing at the conclusion, some of which are followed-up on 25 years later in a sequel entitled "Tracking", serialized in "Analog Science and Fact" magazine in the summer and fall of 2008.The book is a first-person narrative, written in the form of Candy's journal, in what used to be referred to as "telegraphic style", which is based on the means employed by those sending telegrams via Western Union late in the 19th and first half of the 20th centuries to save money.At that time telegrams were the quickest way to transmit hardcopy messages over significant distances.
