It’s been 20 years since the quixotic and worldsweary Louis Wu discovered the Ringworld. Now he and SpeakertoAnimals are going back, captives of the Hindmost, a deposed puppeteer leader. With Louis’ help, the Hindmost intends to regain his status by bringing back such extraordinary treasures from the Ringworld that his fellow puppeteers will have to be impressed. But when they arrive, Louis discovers that the Ringworld is no longer stable - and will destroy itself within months. To survive, he must locate the control center of the legendary engineers who built the planet.

When Lenina and Bernard visit a savage reservation, we experience how Utopia can destroy humanity. Cloning, feel-good drugs, anti-aging programs, and total social control through politics, programming, and media: has Aldous Huxley accurately predicted our future? With a storyteller's genius, he weaves these ethical controversies in a compelling narrative that dawns in the year 632 A.F. (After Ford, the deity). When Lenina and Bernard visit a savage reservation, we experience how Utopia can destroy humanity.

For centuries, men and women have manned lighthouses to ensure the safe passage of ships. It is a lonely job and a thankless one for the most part. Until something goes wrong. Until a ship is in distress. In the twenty-third century, this job has moved into outer space. A network of beacons allows ships to travel across the Milky Way at many times the speed of light. These beacons are built to be robust. They never break down. They never fail. At least, they aren’t supposed to.

Sci-fi's favorite antisocial AI is back on a mission. The case against the too-big-to-fail GrayCris Corporation is floundering, and more importantly, authorities are beginning to ask more questions about where Dr. Mensah's SecUnit is. And Murderbot would rather those questions went away. For good. Martha Wells' Rogue Protocol is the third in the Murderbot Diaries series, starring a humanlike android who keeps getting sucked back into adventure after adventure, though it just wants to be left alone, away from humanity and small talk.

Leo Graf was just your average highly efficient engineer: mind your own business, fix what's wrong, and move on to the next job. But all that changed on his assignment to the Cay Habitat, where a group of humanoids had been secretly, commercially bioengineered for working in free fall. Could he just stand there and allow the exploitation of hundreds of helpless children merely to enhance the bottom line of a heartless mega-corporation?

The Ringworld is a landmark engineering achievement, a flat band 3-million-times the surface area of Earth, encircling a distant star. Home to trillions of inhabitants, not all of which are human, and host to amazing technological wonders, the Ringworld is unique in all of the universe.

The witnesses are legion, scattered across the world and dotted through history, people who looked up and saw something impossible lighting up the night sky. What those objects were, where they came from, and who - or what - might be inside them is the subject of fierce debate and equally fierce mockery, so that most who glimpsed them came to wish they hadn't. Most, but not everyone.

Signs of life have been found on Titan, Saturn’s largest moon. A group of visionaries led by NASA’s Paula Benacerraf plan a daring one-way mission that will cost them everything. Taking nearly a decade, the billion-mile voyage includes a ‘slingshot’ transit of Venus, a catastrophic solar storm, and a constant struggle to keep the ship and crew functioning. But it is on the icy surface of Titan itself that the true adventure begins. In the orange methane slush, the astronauts will discover the secrets of life’s origins and reach for a human destiny beyond their wildest dreams.

The Federation's military command is desperate, and with their fleet still in tatters, they make a last-ditch effort to free the planet: They pull Captain Jackson Wolfe out of retirement and put him in command of a ship they hope can get past the defending armada and provide support to the beleaguered Marines and civilians fighting on the surface of the contested world. There is no reasoning with this enemy. If the Terran Federation wants their planet back, they will have to pay the price.

When Jack Harrison climbed down the short ladder from the airlock and stepped onto the debris covered soil, the ground crackled with the sound of dried leaves and twigs.

Captain Jason Burke is a man apart, and not just because he's the only of his kind for thousands of light-years in any direction. The changes to his body and to his genetic code have made him faster, stronger, more able to survive in his dangerous occupation...but they've also ensured that he'll never truly fit in with others of his species. He always assumed he would live and die with his crew and never lay eyes on another human again. He was wrong.

With the power gone, the UK falls into a state of panic. The ensuing anarchy is simply the warm-up act.

What would you do if the lights went out?

Welcome to Ringworld, an intermediate step between Dyson Spheres and planets. The gravitational force created by a rotation on its axis of 770 miles per second means no need for a roof. Walls 1,000 miles high at each rim will let in the sun and prevent much air from escaping. Larry Niven's novel, Ringworld, is the winner of the 1970 Hugo Award for Best Novel, the 1970 Nebula Award for Best Novel, and the 1972 Ditmars, an Australian award for Best International Science Fiction.

Murderbot wasn’t programmed to care. So, its decision to help the only human who ever showed it respect must be a system glitch, right? Having traveled the width of the galaxy to unearth details of its own murderous transgressions, as well as those of the GrayCris Corporation, Murderbot is heading home to help Dr. Mensah—its former owner (protector? friend?)—submit evidence that could prevent GrayCris from destroying more colonists in its never-ending quest for profit. But who’s going to believe a SecUnit gone rogue? And what will become of it when it’s caught?

No one has ever ventured deeper into space than the four astronauts of Shepherd-1. The aim of their mission is to witness the creation of the cosmos. Using the sun as a lens, they are to align a flock of probes in such a way that the moment of the Big Bang becomes visible. For astronomer Christine, this is a dream come true. So she is bitterly disappointed when the first images are obscured by a kind of veil that prevents any insight. She works obsessively to find a solution, but when she finally succeeds in lifting the veil, she sees something that would have been better kept hidden...

Obstacles arise every step of the way, forcing compromise and sacrifice. And not everyone on his ship is pure of heart. The bonds he forges on the journey will be the key to surviving on another world—a world anyone has yet to fully explore.
