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.

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.

How do you get to the Red Planet? Not via a benightedgovernment program trapped in red tape and bound by budget constrictions,that's for sure. No, what it will take is a helping of adventure, science,corporate power plays, a generous dollop of seduction - both in and out of theboardroom - and money, money, money!

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.

In a startling future that's coming closer every year, Chet Kinsman is an astronaut ace who has done everything one can in space - including commit the first murder.

A series of shocking yet strangely inevitable circumstances will force Kinsman to confront his hidden past and decide Earth's destiny. In a desperate countdown to nuclear annihilation, Kinsman will struggle against a deadly dilemma: if he rescues the world, he risks destroying himself.

We were fighting on the wrong side of a war we couldn't win. And that was the good news. The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

NASA finally made it. The very first human has just set foot on the surface of our neighbor planet. This is the start of a long research expedition that sent four scientists into space. But the four astronauts of the NASA crew are not the only ones with this destination. The privately financed "Mars for Everyone" initiative has also targeted the Red Planet. Twenty men and women have been selected to live there and establish the first extraterrestrial settlement.

High above the planet Harmony, the Oversoul watches. Its task, programmed so many millennia ago, is to guard the human settlement on this planet, to protect this fragile remnant of Earth from all threats...to protect them, most of all, from themselves.

The mission is simple. Escort an emissary to an intergalactic peace summit. Try not to get in the way. Lt. Magnus and his 79th Recon Team have certainly handled worse, after all.

Worse still, a dying alien chieftain gives them a priceless drive of intel, marking them for death. The mission has officially changed. With enemies on all sides, Magnus must do everything in his power to protect the emissary and escape the tower.

Get ready to experience two more origin stories in the Backyard Starship universe.

When an experiment to study quantum uncertainty goes spectacularly wrong, physics student Bill Rustad and his friends find that they have accidentally created an inter-dimensional portal. They connect to Outland - an alternate Earth with identical geology, but where humans never evolved. The group races to establish control of the portal before the government, the military, or evildoers can take it away. Then everything changes when the Yellowstone supervolcano erupts in an explosion large enough to destroy civilization and kill half the planet.

Young Alvin was born the seventh son of a seventh son. By his birthright, he possesses magical powers and is destined to become something great, perhaps even a Maker. Indeed, Alvin is special. But the boy remains vulnerable to dark forces who reach out to destroy him and are willing to do anything to keep him from growing up. Carefully weaving the lore and the folk-magic of the men and women who settled a continent—as well as the beliefs of the tribes who were there before them—Orson Scott Card has created a fascinating alternate frontier America.

A secret buried in the Antarctic. A puzzle unsolved for thousands of years. And a Brooklyn-born master gunnery sergeant who's royally pissed that he has to babysit the researchers sent to figure it all out. But when Patrick "Wic" Finnegan finally sees what the team has uncovered, he can't believe his eyes, nor is he prepared for the violence to come. Soon, the portal opens and unleashes a storm of unbridled fury upon humanity.
