The Dragon, an enormous comet, is on a trajectory that will bring it perilously close to an Earth that is still suffering from the scars of a nuclear incident, and from the problems of the Greenhouse Effect. For the optimists - those that remain - it is a sign of change for the better; for others, the comet foreshadows humanity's final doom. But to Francis Reese and the hard-pressed astronauts of the depleted space programme, the Dragon presents a third outrageous, yet irresistible possibility - the transformation of a barren world into a new home for the beleaguered peoples of Earth.

Nobel Prize-winning scientist Richard Lee has stirred up fanatical religious hatred with his controversial theory that chimpanzees and humans may have shared a common ancestor as little as three million years ago. When this hatred loses him both his reputation and his beloved colleague Marjorie, Lee retreats into hiding with his experiments and with Adam, an apelike creature thought by some to be Lee's own deformed love-child, or even a kind of Frankenstein's monster. But Adam is growing up, and the astonishing secret of his genetic parentage cannot remain secret forever, especially once investigative journalist Louise Henderson scents a story in the remote Norfolk village where Lee has gone to earth.

Frank Rhind was lucky. He saw the Ice Dancer and lived. The town of Hays died. And still they didn't believe Dr. William Stovin's warnings. For very many years climatologists had been predicting a change in the world's climate but they always believed that the process would take centuries. Now there was a reason to believe differently. Stovin had staked his career and credibility on trying to persuade the U.S. National Science Council to act, but 15,000 years of warmth had lulled mankind into thinking that climatic history was over. Already it was too late. The new Ice Age had begun. One by one the great northern cities - Chicago, Oslo, Montreal, Moscow, Leningrad - came under siege. Some fell and were evacuated, sending their young, old and sick to crowded areas further south. Crops and animals were destroyed. Governments drew lines of catastrophe across their national maps. Doomsday prophets were in full cry. Technological man was overwhelmed. The world had changed. Some time in the year future the next Ice Age will be triggered off. It could happen in a thousand years' time, or in a century from now. Or it could, quite literally, happen next winter. This book is fiction only because the events described have not yet happened. But it is not science fiction because all the science in the book is fact. When the year arrives that we see the sixth winter resembling 1792 within the space of a decade or so, then the Ice Age will be with us in a matter of weeks - and it will develop very much as described here.

The Earth does not belong to man alone The Himalayas bury their secrets well. Two skulls unearthed in the cradle of the human race - the remote heights of Kashmir - throw evolutionary theory into chaos. But a far more disturbing secret lies hidden deep in the bleak mountains and snow-swept valleys unseen by human eyes. A few miles from the explosive triangle of tension where Afghanistan and Pakistan border on India the story of the century breaks. And the echoes of the most shattering revelation yet made to man threaten to plunge the world into total war which will turn the cradle of the human race into its final grave.

It is over a thousand years since the events of Double Planet, when a group of cosmonauts crashed a comet into the Moon, thereby bringing a potential life-supporting atmosphere to that desolate planet. Tugela is a young girl who has grown up in the austere post-technological society that has settled there in that time, a society dominate by the all-powerful City and its insidious cult of the Eye. As the comets stopped coming, and the atmosphere became increasingly thin, the Priests' power grew with the claim that only their rituals could bring the comets back. But a revolution is brewing among the Moon colony that aims to smash both the City and the poisonous stranglehold of superstition that has been holding it back for so long. Within this violent struggle, Tugela has a vital role to play. When she stumbles into a secret vital to the cause, she soon realises her destiny lies far beyond her homeland, beyond the deadly Forbidden Zone, perhaps even beyond the Moon itself...

Because of the length of time that a voyage takes, knowledge of the purpose and nature of the universe often becomes lost to the succeeding generations of starship occupants. Through the experiences of a woman, and the people she encounters in a journey, the truth of their existence is revealed.

The day of ice and fire, that brings in its wake devastation to the world. Dr Robert Graham, noted nuclear physicist, has campaigned hard and long for disarmament. Now his patience is at an end. With an ill-assorted handful of desperate, like-minded 'terrorists', he plans to hold the human race to ransom. His bargaining power is terrifying - nothing short of Ragnarok itself. The world governments must listen - or the countdown to nuclear winter has already begun . . .
