The book was originally due to be published as book 20 in the Usborne Puzzle Adventure series. A detailed plot outline was written, cover art created, ISBN's were allocated[1] and the title was printed in the series list on the back of other Puzzle Adventure books[2]. However, due to the lack of interest at trade fairs[1], Usborne decided not to go ahead with continuing the book to completion[3] at that time. It remains unpublished.

Due to the fact it has an ISBN, catalogue entries can be found in catalogues and on the internet.
