By the year 2050, great advances have been made in the realm of computer science, but the most sophisticated computer ever to have been built is about to be revealed to the world. The brainchild of Professor James Parton, a computer scientist, and Professor Maureen Hartley, a neurologist, Astra, by breaching the divide between inanimate machine and human consciousness, will lead not only these two brilliant Cambridge scientists and their PhD research assistant, Chester Wilkins, into strange and new dimensional experiences of space and time, but the whole of humanity to the very brink of extermination. Parton, Hartley, Wilkins and their team soon find themselves working against the clock to save the entire human race from what seems to be certain doom. With a bizarre potpourri of methods as diverse as they are seemingly unrelated, they set out on an adventure which is as exciting as it is dangerous.
