There are some who want to improve it. There are some who want to eradicate it. And there are others who just want to exploit it.When a young scientist is caught improving Nexus, he’s thrust over his head into a world of danger and international espionage – for there is far more at stake than anyone realizes.From the halls of academe to the halls of power, from the headquarters of an elite US agency in Washington DC to a secret lab beneath a top university in Shanghai, from the underground parties of San Francisco to the illegal biotech markets of Bangkok, from an international neuroscience conference to a remote monastery in the mountains of Thailand – Nexus is a thrill ride through a future on the brink of explosion.

    Now, as faster-than-light drive opens the stars to exploration, humans are finding other relics of the race they call the Monument-Makers - each different, and each heartbreakingly beautiful. But except for a set of footprints on Jupiter's moon Iapetus, there is no trace of the enigmatic race that has left them behind. Then a team of scientists working on a dead world discover an ominous new image of the Monument-Makers. Somehow it all fits with other lost civilizations, and possibly with Earth's own future. And distant past. But Earth itself is on the brink of ecological disaster - there is no time to search for answers. Even to a question that may hold the key to survival for the entire human race...

    Machines soared through the air, churned through the seas, crawled across the surface, pushing ever forward, carrying death. Earth was engaged in titanic struggle. Germany, Russia, France, China, Japan: the maps were changing day by day. The hostilities spread in ever-widening ripples of destruction: Britain, Italy, Africa...The fate of the world hung in the balance. Then the real enemy came. Out of the dark of night, out of the soft glow of dawn, out of the clear blue sky came an invasion force the likes of which Earth had never known - and worldwar was truly joined. The invaders were inhuman and they were unstoppable. Their technology was far beyond our reach, and their goal was simple. Fleetlord Atvar had arrived to claim Earth for the Empire. Never before had Earth's people been more divided. Never had the need for unity been greater. And grudgingly, inexpertly, humanity took up the challenge. In this epic novel of alternate history, Harry Turtledove takes us around the globe. We roll with German panzers; watch the coast of Britain with the RAF; and welcome alien-liberators to the Warsaw ghetto. In tiny planes we skim the vast Russian steppe, and we push the envelope of technology in secret labs at the University of Chicago. Turtledove's saga covers all the Earth, and beyond, as mankind - in all its folly and glory - faces the ultimate threat; and a turning point in history shows us a past that never was and a future that could yet come to be...

    But that’s what backup hard drives are for. And Li should know; she’s been hacking her memory for fifteen years in order to pass as human.

A dead physicist who just happens to be her cloned twin. A missing dataset that could change the interstellar balance of power and turn a cold war hot. And a mining “accident” that is starting to look more and more like murder...Suddenly Li is chasing a killer in an alien world miles underground where everyone has a secret. And one wrong turn in streamspace, one misstep in the dark alleys of blackmarket tech and interstellar espionage, one risky hookup with an AI could literally blow her mind.

    Humanity’s greatest dreams have become reality. Along with dozens of other sentient races, the people of Earth have formed the United Federation of Planets—a galactic civilization that governs much of the known universe for the good of all. Over the past two centuries, mankind has tamed its basest instincts, and reached the stars…But suppose it hadn’t happened that way at all? Suppose instead humanity’s darkest impulses, its most savage, animalistic desires had triumphed? Suppose that the empire mankind made out in the stars was one ruled by terror, where only those willing to brutalize their own kind and their neighbors could survive?One hundred years ago, four crewmembers of the U.S.S. Enterprise crossed the dimensional barrier and found just such an empire. A mirror image of their own universe, populated by nightmare duplicates of their shipmates. Barely able to escape with their lives, they returned thankful that the accident that brought them there could not be duplicated. Or so they thought.But now the scientists of that empire have found a doorway into our universe. Thier plan: to destroy from within, to replace one of our starships with one of theirs. Their victims: the crew of the U.S.S. Enterprise NCC 1701-D.
