Returning to the Cavendish Laboratory in Cambridge after a spell at the nuclear research labs of CERN in Geneva, Professor Isaac Newton is plunged into the centre of a baffling mystery. One of his research students, Mike Howarth, has picked up strange signals on his satellite telemetry equipment, signals that appear to emanate from a passing comet. Not long after he has passed the vital data into Isaac Newton’s hands, Howarth is found dead. Soon after that, it becomes clear that some people in very high places – including the Kremlin and the White House – are more than a little interested in the remarkable events taking place at the Cavendish. But with the arrival of that most majestic of all celestial bodies, Comet Halley, a third and infinitely more powerful superpower enters the scene. And the Comet’s extraordinary intentions – not to mention its devastating methods of communicating them to Earth – promise a new dawn for humanity.
In 1986, Halley’s Comet returned to our heavens for the first time in over seventy-five years. Heart of the Comet is the story of Halley’s next return in the middle of the twenty-first century, and of a daring mission to explore and colonize this ice-covered wanderer. It is the thrilling saga of a multinational group of exiles who discover the comet’s astonishing secret – the secret that threatens their very survival.
