The book does not really follow the pattern of the other Red Dwarf books where it's split up into linked sub-stories, where each sub-story expands on a certain Red Dwarf episode.
It stands out on its own as a book and not just an expansion of a few Red Dwarf episodes (there's nothing wrong with this). There are a couple charaters brought in from the show (e.g. Kinotowowi from Emohawk) but nothing else directly.
The story itself is excellent, well thought out, unpredictable and does not have that feel good factor of the TV show. It is dark and has a sinister element to it.
It is definately worth getting as it gets a big tick in two boxes: for those who have a thirst for Red Dwarf and for those who want a good book with a strong story.
