The process of 'Passengering' is the method of using remote pair tunnelling electrons to travel great distances in a very short time. An individual's mind is stored electronically, then transmitted almost instantly to the body of a host, which might be someone you are swapping with, or a clone of yourself. The tunnelling electrons allow the transmission to be virtually instantaneous over many light years.
The novel Passengers to Sentience, first published in 2009, told the story of cyber detective Ben taking a holiday by swapping bodies with criminal prosecutor Lori. In the future they both inhabit, transferring mind patterns between bodies over huge interstellar distances is relatively commonplace. It is the transfer process which allowed human colonisation of an outer arm of the galaxy. The system is highly secure and there is no possibility of ending up in the wrong body, or so everyone thought.
Passengers to Zeta Nine is a story set in a quiet backwater, a part of space remote from Ben and Lori's struggles. Human colonies are spread thinly but there are still new planets to find and colonise. For pioneers Raife and Doctor Nancy Zing, the computer aboard their Explorer-class ship has made an exciting choice.
Explorer 5017 set off almost a hundred years before Ben and Lori were born. The ship finally located a habitable planet at almost exactly the time Ben and Lori made contact with the Sentience. Thus Ben and Lori, Nancy, Raife, Riajh and Tinc are entirely contemporary, if not by birth.
The sequel to Passengers to Sentience, Sentience Revelations, will explore Ben and Lori's involvement with cultural and commercial exchange between humans and an alien culture. The fact that each race breathed an atmosphere poisonous to the other is thought to be protection enough against invasion of each other's space.
