Two hundred thousand feet up, things go horribly wrong. An experimental low-orbit spaceplane breaks up on reentry, falling to earth over a trail hundreds of miles long. And in its wake is the beginning of the most important mission in the history of spaceflight.

When Kell and his team return to Earth many years after their departure, they find that their world has changed almost beyond recognition. Not only has a second wave of greenhouse flooding caused sea levels to rise, but society has been changed by the consequences of the climate shift. Few people want to face Jordan Kell's news. He must convince Earth's new rulers that the human race is in danger of extinction unless it acts to forestall the death wave coming from the galaxy's heart.

Here are tales of star-faring adventure, peril, and drama. Here are journeys into the mind-bending landscapes of virtual worlds and alternate realities. Here you'll also find stories of humanity's astounding future on Earth, on Mars, and in the solar system beyond - stories that always get the science right. And Bova's gathering of deeply realized, totally human characters are the heroic, brave, tricky, sometimes dastardly engineers, astronauts, corporate magnates, politicians, and scientists who will make these futures possible.

Dr. Jake Ross, a university astronomer, wants nothing more than to teach a few classes each semester and continue his research. Instead, he finds himself aggressively recruited to be the science advisor to Frank Tomlinson, an ambitious politician with his eye on the US Senate. Tomlinson is in need of an edge that will allow him to defeat his opponent at the polls, and Dr. Ross can contribute just that: MHD. MHD, or magnetohydrodynamics, is a new innovation that will allow electricity to be generated efficiently and cheaply. But MHD is still in its infancy, and there are deadly risks.

When a nuclear missile launched by a rogue North Korean faction explodes in space, the resulting shock wave destroys most of the world’s satellites, throwing global communication into chaos. U.S. military satellites, designed to withstand such an assault, show that two more missiles are sitting on launch pads in North Korea, ready to be deployed. Faced with the threat of a thermonuclear attack, the United States has only one possible defense: Able One.

A hero without peer or scruples, Sam Gunn has a nose for trouble, money, and women, though not necessarily in that order. A man with the ego (and stature) of a Napoleon, the business acumen of a P. T. Barnum, and the raging hormones of a teenage boy, Sam is the finest astronaut NASA ever trained and dumped. But more than money, more than women, Sam Gunn loves justice—and he really does love money and women.

Stoner knew. The fiery object hurtling toward the Earth was an alien spacecraft. But the world might never know. He was trapped in an iron cordon of secrecy, for the discovery had shattered the world power balance, setting off a brutal struggle for supremacy that raged from the sacred halls of the Vatican to the corridors of the Kremlin and the Pentagon. The forces of fear and treachery would use any weapon at their command, from mind war to sabotage, to keep the world in darkness.

In a scrap heap within an abandoned factory, the greatest invention in history lies dormant and unused. By what fatal error of judgment has its value gone unrecognized, its brilliant inventor punished rather than rewarded for his efforts? In defense of those greatest of human qualities that have made civilization possible, one man sets out to show what would happen to the world if all the heroes of innovation and industry went on strike.

There are some odd things about Nate’s new apartment. Of course, he has other things on his mind. He hates his job. He has no money in the bank. No girlfriend. No plans for the future. So while his new home isn’t perfect, it’s livable. The rent is low, the property managers are friendly, and the odd little mysteries don’t nag at him too much. At least, not until he meets Mandy, his neighbor across the hall, and notices something unusual about her apartment. And Xela’s apartment. And Tim’s. And Veek’s.

On November 22, 1963, three shots rang out in Dallas, President Kennedy died, and the world changed. What if you could change it back? In this brilliantly conceived tour de force, Stephen King - who has absorbed the social, political, and popular culture of his generation more imaginatively and thoroughly than any other writer - takes listeners on an incredible journey into the past and the possibility of altering it.

On an entirely normal, beautiful fall day in Chester's Mill, Maine, the town is inexplicably and suddenly sealed off from the rest of the world by an invisible force field. Planes crash into it and fall from the sky in flaming wreckage, a gardener's hand is severed as "the dome" comes down on it, people running errands in the neighboring town are divided from their families, and cars explode on impact. No one can fathom what this barrier is, where it came from, and when - or if - it will go away.

Jazz Bashara is a criminal. Well, sort of. Life on Artemis, the first and only city on the moon, is tough if you're not a rich tourist or an eccentric billionaire. So smuggling in the occasional harmless bit of contraband barely counts, right? Not when you've got debts to pay and your job as a porter barely covers the rent. Everything changes when Jazz sees the chance to commit the perfect crime, with a reward too lucrative to turn down.

It’s been twelve years since the 2040 Quake rocked the Golden State, fracturing Los Angeles and the fortunes of millions. It’s been six years since tech billionaire Damon Yates founded his elite academy, giving Unfortunates from the wrong side of his hyperloop tracks a new future at Quest Campus, tucked away in the Santa Monica Mountains. But an endeavor that sought to bridge a divide only tore eighteen-year-old twin sisters apart.

The Galahad, a faster-than-light spacecraft, carries 50 scientists and engineers on a mission to prepare Kepler 452b, Earth's nearest habitable neighbor at 1400 light years away. With Earth no longer habitable and the Mars colony slowly failing, they are humanity's best hope. After 10 years in a failed cryogenic bed - body asleep, mind awake - William Chanokh's torture comes to an end as the fog clears, the hatch opens, and his friend and fellow hacker, Tom, greets him...by stabbing a screwdriver into his heart. This is the first time William dies.

John Perry did two things on his 75th birthday. First he visited his wife's grave. Then he joined the army. The good news is that humanity finally made it into interstellar space. The bad news is that planets fit to live on are scarce—and alien races willing to fight us for them are common. So: we fight. To defend Earth, and to stake our own claim to planetary real estate. Far from Earth, the war has been going on for decades: brutal, bloody, unyielding. Earth itself is a backwater.
