With the re-publication of this novel, Koontz revised and expanded the text from the first edition and labeled it “Part One” and included additional text and labeled it “Part Two”.  Part Two ends with “…but that was not the year our secret war with the goblins ended” implying a “Part Three” which has yet to be published.

The Berkley and W.H. Allen editions have a slightly different version of Part One.

Both the UK hardcover and US paperback editions state “A slightly different version of Part One of TWILIGHT EYES was published in a special illustrated hardcover edition for collectors by The Land of Enchantment in November 1985.  This is the first publication of the complete story.” However, both cannot be the “first”.

The cover of the W.H. Allen hardcover edition is featured on page 455 of Art of Imagination.
