His name was Biron Farrill and he was a student at the University of Earth. A native of one of the helpless Nebular Kingdoms, he saw his home world conquered and controlled by the planet Tyrann - a ruthless, barbaric Empire that was building a dynasty of cruelty and domination among the stars. Farrill’s own father had been executed for trying to resist the Tyrann dictatorship and now someone was trying to kill Biron. But why? His only hope for survival lay in fleeing Earth and joining the rebellion that was rumored to be forming somewhere in the Kingdoms.

Two irresistible forces are rushing together to crush the planet Grayson between them, and only one woman, uncertain of her capabilities, weary unto death, and marked for murder -stands between her adopted planet and its devastation.

Merritt Alder is done with Earth. The planet is polluted and overpopulated, and its people are hungry. Earth's first colony, Galena, is a pioneer world 10,000 light-years away. It has clean air, unpolluted water, and continents of arable land. Anyone can start a new life…if they can get there. For Merritt, the journey is only the beginning. Obstacles arise every step of the way, forcing compromise and sacrifice. And not everyone on his ship is pure of heart.

Rebels build a secret base on Green World. Their plan is to attack Earth and retake all the planets the humans have conquered.

When James McGill stumbles onto the rebel camp, they’re forced to step up their plans. The world goes up in flames. Friends are permed and cities are destroyed as everything spins out of control.

For decades, the spacefaring species of known space have battled over the largest artifact - and grandest prize - in the galaxy: the all-but-limitless resources and technology of the Ringworld. Now, without warning, the Ringworld has vanished, leaving behind three rival war fleets. If the fallen civilization of the Ringworld can no longer be despoiled of its secrets, the puppeteers will be forced to surrender theirs - everyone knows that they are cowards. But the crises converging upon the trillion puppeteers of the Fleet of Worlds go far beyond even the onrushing armadas.

In a plot to steal his business, his greedy partner and greedier fiancée tricked him into taking the "long sleep": suspended animation for 30 years.

The UFS Phoenix returns to Homeworld, after more than three years of searching the galaxy for a way to save humanity from the looming AI threat. Many Fleet captains are unhappy with their own command, following the massive casualties of Nia's first strike. Some say that Captain Erik Debogande is the war leader humanity truly needs.

A secret that could tear Fleet, and Erik's powerful family, apart.

On a cold spring night in 1952, a huge meteorite fell to earth and obliterated much of the East Coast of the US, including Washington, DC. The ensuing climate cataclysm will soon render the Earth inhospitable for humanity, as the last such meteorite did for the dinosaurs. This looming threat calls for a radically accelerated effort to colonize space and requires a much-larger share of humanity to take part in the process. Elma York’s drive to become the first lady astronaut is so strong that even the most dearly held conventions of society may not stand a chance against her.

In the 1800s, a sailing ship crashes off the coast of Norway. In the 1900s, a Zepellin explores an icy canyon in Antarctica. In the far future, a spaceship sets out for an alien artifact. Each excursion goes horribly wrong. And on every journey, Dr. Silas Coade is the physician, but only Silas seems to realize that these events keep repeating themselves. And it's up to him to figure out why and how. And how to stop it all from happening again.

Mary Robinette Kowal continues the grand sweep of alternate history begun in The Calculating Stars. The Fated Sky looks forward to 1961, when mankind is well established on the moon and looking forward to its next step: journeying to, and eventually colonizing, Mars. Of course the noted Lady Astronaut Elma York would like to go, but there’s a lot riding on whoever the International Aerospace Coalition decides to send on this historic - but potentially very dangerous - mission. Could Elma really leave behind her husband and the chance to start a family to spend several years traveling to Mars?

They hunt us. They bomb our worlds for target practice. A star cluster in the constellation of Orion rotates once every 1,000 years. Those who rule there have an ancient tradition: When each cycle ends, they train their fleets by spilling the blood of lesser beings. The enemy fleets are coming again. In response, the Rebel Worlds gather their starships to face the terrifying threat, and this time humanity is asked to stand with them. The last time they considered Earth, Vikings in longboats were raiding English coastlines. Today, we're less primitive. Today, we're a target.

The Phage War had been a devastating conflict for the Terran Confederacy. Even with the destruction of their terrifying, implacable foe, humanity is still reeling. Political alliances are crumbling, and their mighty fleet is in tatters. There is nothing to celebrate, even after such a complete victory. They soon learn that there are other stellar neighbors - and they've been watching the conflict with great interest. One species comes with an offer of friendship and alliance, but humanity is weary and distrustful.

Since fleeing the supernova chain reaction at the galactic core, the cowardly Puppeteers of the Fleet of Worlds have - just barely - survived one crisis after another: the rebellion of their human slaves, the relentless questing of the species of Known Space, the spectacular rise of the starfishlike Gw'oth, the onslaught of the genocidal Pak. Now fresh disaster looms, as though past crises have returned and converged. Who can possibly save the Fleet this time?

From Joshua Dalzelle comes the follow-up to the number-one best seller Warship. Captain Jackson Wolfe survived the initial incursion of a vicious alien species into human space...barely. He had assumed the juggernaut that had devastated three Terran systems was the herald for a full invasion, but for the last few years it has been eerily quiet along the Frontier. Jackson now struggles to convince the Confederate leadership the threat is still imminent and needs to be taken seriously.

When unforeseen circumstances during an innovative—and unsanctioned—commercial asteroid-mining mission leave two crew members stranded, those who make it back must engineer a rescue, all while navigating a shifting web of global political alliances and renewed Cold War tensions. With Earth governments consumed by the ravages of climate change and unable to take the risks necessary to make rapid progress in space, the crew must build their own next-gen spacecraft capable of mounting a rescue in time for the asteroid's next swing by Earth.

Titan is practically a planet in its own right, with a diameter similar to that of Mercury, methane rainstorms, organic soot, and ethane seas. The views from Titan’s Mayda outpost are spectacular, but all is not well at the moon’s remote science base. On the shore of a methane sea beneath glowering skies, atmospherics researcher Abigail Marco finds herself in the middle of murder, piracy, and colleagues who seem to be seeing sea monsters and dead people from the past.
