A Fire Upon the Deep is the big, breakout book that fulfills the promise of Vinge's career to date: a gripping tale of galactic war told on a cosmic scale. Thousands of years hence, many races inhabit a universe where a mind's potential is determined by its location in space, from superintelligent entities in the Transcend, to the limited minds of the Unthinking Depths, where only simple creatures and technology can function.

Rachel Adams beobachtet das All mit Hilfe des Chandra-Röntgensatelliten. Als ihr Kollege Shawn Whitfield sie bittet, ein kosmisches Phänomen zu untersuchen, sagt sie zu – nicht ahnend, dass das Routine-Projekt ihr Leben dramatisch verändern wird. Denn schnell stellt sich heraus, dass Shawn keinen simplen Asteroiden gefunden hat – das Objekt scheint keinen natürlichen Ursprung zu haben. Rachels Neugier ist geweckt, und selbst, als man ihr das Projekt als nationale Verschlusssache wegnimmt, ist sie nicht zu bremsen. Und dann bewegt sich das Objekt auch noch auf die Erde zu!

The day that changed Melody's life was like any other over the previous two years. She'd found she had a gift for writing, and her career as an author had almost healed the pain of losing her job. When the Secret Service rang her bell, everything changed. Something was nearing Saturn…and it was slowing down. Had she been right about the object?

A crescent moon set against a jeweled field of stars gracefully slid into view. The thin arc of its crater-filled landscape drew Jack’s mind in. His eyes followed the long, inky shadows cast by jagged crater walls as they cut sharply into the pockmarked ashen terrain. Deeper within the jet-black lunar night-side were the lonely peaks of a smattering of mountain tops, catching a few last rays of sunlight. All Jack felt was a desire to escape; to be down there exploring...perhaps uncovering some new detail in the history of Earth’s nearest neighbor.

In 2014, the ESA spacecraft Rosetta lands a small probe named Philae on 67P, a Jupiter-family comet. The lander goes radio-silent two years later. Suddenly, in 2026, scientists receive new transmissions from the comet. Motivated by findings that are initially sensational but soon turn frightening, NASA dispatches a crewed spacecraft to the comet. But as the ship approaches the mysterious celestial body, the connection to the astronauts soon breaks. Now it seems nothing can be done anymore to stop the looming dark danger that threatens Earth....

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.

The Dusahn Empire has been contained for the moment. But there is much work to be done in order to keep them from reasserting their dominance over the Pentaurus sector. As much as Captain Scott wants to see the Empire destroyed, he may have no choice but to find a way to coexist with them.

A planet in the endless emptiness of space, far from the warmth of any sun. And yet there are people who populate its vast caverns, living, working and loving. Since time immemorial, they have been on course for Andromeda, the neighboring galaxy of the Milky Way. This is the prophecy of the ancients, the one goal that unites them all, their cult. But then the unthinkable happens: the journey stops because the planet enters the orbit of a mysterious object that can't be seen in any telescope.

Theodore und sein Team müssen in Los Angeles in die Höhle des Löwen gelangen, um Geheimnisse aufzudecken, die nicht nur sein Leben zerstört haben, sondern möglicherweise die einer ganzen Generation: Ihr Weg führt in den Cerberus.

Im Herzen feindlichen Gebiets finden sie eine Verschwörung, die bis nach Ganymed reicht und plötzlich wird das nackte Überleben zum einzigen Ziel.

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.

On Mars, terraforming breakthroughs leave citizens dreaming of a transformed planet. However, when a contaminated ice asteroid puts water supplies in peril, the dream quickly shatters. Professor Zambrotta "Zammi" Kaspar is tasked to investigate a fatal crash on a remote ice asteroid, but he never expects to discover his missing sister there as an indentured worker for the Mining Guild. As the siblings reconnect and dig deeper into the mystery of the contaminated water, they both discover a personal legacy of secrets and loss over competing visions for the future of humanity.

In the far reaches of the solar system, the outer planets - billions of miles from Earth, unknown for millennia - are being settled. Neptune, the ice giant, is swathed in clouds of hydrogen, helium, and methane and circled by rings of rock and dust. Three years ago, Ilona Magyr’s father, Miklos, disappeared while exploring the seas of Neptune. Everyone believes he is dead - crushed, frozen, or boiled alive in Neptune’s turbulent seas.
