As is usual, there are many people and numerous sources of knowledge that inspired, informed, or sustained me during the writing of this novel.

The language of the Krat and Annunaki: This is loosely based on Ugaritic Cuneiform Script with some Persian Cuneiform thrown in (I changed the numbering system in the belief that a base of 10, rather than 60, would be a lot easier for calculations that may be required in later books). The grammatical rules were inspired by Afrikaans, while the grammar itself has roots in English, Dutch, Zulu, Xhosa, and Afrikaans. My heartfelt thanks to those excellent web sites that provided not only an understanding of Cuneiform, but also the fonts I required.

The history of Sumer: Once again the numerous web sites and their sheer volume of information was invaluable, if not daunting.

The spaceship engineering: Much of my inspiration came from the non-fiction works of Stephen Hawking, Carl Sagan, Larry Niven, Arthur C. Clarke, Peter Nicholls and numerous web sites. In addition, the fiction of countless authors gave me the guts to attempt the impossible i.e. to invent my version of ‘Hyperspace’.

The medical side: The work by Matt Ridley provided one of the missing pieces for the series, which had been building in my subconscious for many years. His book on the Genome was truly astounding. Other medical information was gleaned from the many informative Web sites and books available.

Editing: My heartfelt thanks to Louis Smith (AKA Igor DP) who finally got an opportunity to edit my work for a change. The task of writing was greatly eased by Igor’s’ brilliant editing, sarcastic wit and practical insight. Final editing was greatly assisted by Chris Cardin and Wendi Christner (both authors in their own right).
