Now in a new, revised edition, the fourth book of the Nebula Award-winning author's Galactic Center series is a classic tale of man's future and fate--and the greatest mystery from outer space that humanity has ever encountered. Piloting an ancient starship, Killeen and the Bishop tribe escape the mech-ruled world of Snowglade. Seeking refuge on a far away planet, they discover vast wonders-an organic life-form as large as a world, a planet-coring cosmic string, a community of humans ruled by a brutal tyrant, and ultimately an alien race more awesome than any they have encountered. As they battle for survival against these myriad dangers, Killeen and his crew will gain an unforeseen ally-one that may determine humanity's true destiny...

From the Nebula Award-winning author comes a newly revised edition of this story in his classic Galactic Center series. 2076: Technology has propelled the world into a new age of enlightenment. Nigel (from In the Ocean of Night) has left Earth to explore space for alien life. But while on this captivating mission, humanity's birthplace has fallen prey to attack and its seas are seeded with alien lifeforms. Now, Nigel is left to search for the only savior he knows-the one who saved him once before-the alien machine called the "Snark." Having left the solar system and turned traitor to its alien masters, Nigel is unsure of the Snark's new allegiance. Is the Snark a friend? Or will it also turn on Nigel... proving to be a deadly foe?

Reviewing the fundamental instrumental techniques and current observational results, this book unveils the mysteries of the physical processes in the central parsec of our Milky Way: the super-massive black hole embedded in a central stellar cluster as well as the gas and dust in the circumnuclear region. The observations described cover the entire electromagnetic spectrum from decimeter radio-waves to high energy X-ray and ?-rays, and a comprehensive summary of up-to-date astrophysical interpretations is given. The emphasis is put on observational techniques, image processing aspects, and a detailed presentation of the most cutting-edge work carried out in the near-infrared wavelength regime. These recent results include both the first orbits of stars around the central black hole and the multiwavelength variability of the central source.

The third novel in the award-winning author's classic Galactic Center series is available once again. "A challenging, pacesetting work of hard science fiction that should not be missed" (Los Angeles Times). Nearly 100,000 years after first contact with the machines that dominate the universe, a few hundred humans survive. Trapped on Snowglade, a barren world near the center of the galaxy, people like Killeen of Family Bishop and his child Toby are primitive scavengers, homeless and hunted by the ruling "mechs." Then suddenly, a strange cosmic entity-neither organic nor cybernetic nor living matter-reaches out from a black hole to speak with Killeen. But can this fallen descendant of starfarers understand this alien being in time-and seize his only chance to save his family and mankind from final annihilation?

The Nebula Award-winning author's fifth installment of his classic Galactic Center series is reissued in this special edition that contains a teaser chapter from The Sunborn. Trying to escape the relentless mechs, the last humans from planet Snowglade take their ancient starship on a dangerous course straight into the Eater, the black hole at the galactic center. Hungry and desperate, the refugees begin to question the leadership of Captain Killeen, who believes the center holds their one hope of survival. Meanwhile, Killeen's son Toby struggles with the microchips that were implanted in his spine-a technology that now threatens his sanity. Caught between their genocidal pursuers and peril in the galactic center, Killeen and Toby bring humanity to its final destiny.

This new, special edition of the classic concluding volume of this defining series by the eminent physicist and Nebula Award-winning author contains a teaser chapter from Benford's, The Sunborn. The final chapter of humanity's future has begun, and three men hold the key to survival. As the fierce, artificially intelligent mechs pursue their savage and unstoppable destruction of the human race, it soon becomes apparent that three men-three generations in a family of voyagers-are their targets. Toby Bishop, his father Kileen, and his longdead grandfather each carry a piece of the lethal secret that can destroy their relentless pursuers. There is only one problem: They have no idea they possess the only weapon that can save humanity.
