Earth’s greatest protection will become its biggest threat. When the Confederation gathers a grand armada ostensibly to liberate Earth from the Boxans, the crew of the Athena must stop them before it’s too late. Some species believe they can avoid war and endure the oppression of the Confederation while others choose to resist. The Athena and her crew struggle to keep the Star Alliance from splintering apart by offering them something unthinkable.

Held prisoner by a vicious alien whose race is determined to conquer the galaxy, Zack wakes to find that he is cut off from everything. Zack must figure out a way to escape his captors and a prison full of dangerous aliens to get back to his ship. Did his friends even know he was still alive? Kaylan commands the Athena, Earth's most advanced spaceship. The crew is far from home and caught in an intergalactic war. The Boxans demand that they leave the star system, Xiiginn warships are hunting them, and the Athena is hopelessly outclassed.

Six months ago, Connor learned what the alien race that populated New Earth feared - a mysterious enemy who nearly brought about the collapse of an entire civilization. To help the colony prepare for this new threat, Connor rejoins the Colonial Defense Force. Using alien technology, Connor opens a gateway to another universe hoping to learn more about the threat. Instead, he receives a colonial distress beacon. Six months ago, they’d left people behind on a mission, all presumed dead. The beacon might be them, or it might be a trap, but Connor will not ignore the call for help.

After narrowly defeating the invading enemy fleet, there is evidence that the attack isn't over. Thousands have died, and all that stands between human extinction and the invaders are the remnants of the colonial military. Connor must find a way to rally the colony using every scrap of ingenuity to stop the invaders. But will he succeed when he finds himself pitted against mankind's ultimate enemy?

Escaping wrongful imprisonment wasn't something Connor had in mind, but being put into stasis aboard Earth's first interstellar colony ship was something he couldn't have prepared for. For 300,000 colonists, the new colony brings the promise of a fresh start...a second chance. Connor might be the wrong man for the colony, but he's the right man to see that it survives what's coming.

2057. Humanity has raised exploiting the solar system to an art form. Bella Lind and the crew of her nuclear-powered ship, the Rockhopper, push ice. They mine comets. And they're good at it. The Rockhopper is nearing the end of its current mission cycle, and everyone is desperate for some much-needed R & R, when startling news arrives from Saturn: Janus, one of Saturn's ice moons, has inexplicably left its natural orbit and is now heading out of the solar system at high speed.

In an Arizona desert a man wanders in a daze, speaking words that make no sense. Within twenty-four hours he is dead, his body swiftly cremated by his only known associates. Halfway around the world archaeologists make a shocking discovery at a medieval site. Suddenly they are swept off to the headquarters of a secretive multinational corporation that has developed an astounding technology. Now this group is about to get a chance not to study the past but to enter it.

In a rare blend of scientific insight and writing as elegant as the theories it explains, Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of 11 dimensions where the fabric of space tears and repairs itself, and all matter-from the smallest quarks to the most gargantuan supernovas-is generated by the vibrations of microscopically tiny loops of energy.

A classic thriller from #1 New York Times bestselling author Michael Crichton, Sphere is a bravura demonstration of what he does better than anyone: riveting storytelling that combines frighteningly plausible, cutting-edge science and technology with pulse-pounding action and serious chills.

There was a time when “universe” meant all there is. Everything. Yet, in recent years discoveries in physics and cosmology have led a number of scientists to conclude that our universe may be one among many. With crystal-clear prose and inspired use of analogy, Brian Greene shows how a range of different “multiverse” proposals emerges from theories developed to explain the most refined observations of both subatomic particles and the dark depths of space.
