The Jedi Council has sent Depa Billaba - Mace’s former Padawan and fellow Council member - to Haruun Kal to train the local tribesmen as a guerrilla resistance force. But now the Separatists have pulled back, and Depa has not returned. The only clue to her disappearance is a cryptic recording left at the scene of a brutal massacre: a recording that hints of madness and murder and the darkness in the jungle...a recording in Depa’s own voice. Mace Windu trained Depa. Only he can find her. Only he can learn what has changed her. Only he can stop her. He will leave behind the Republic he serves, the civilization he believes in, everything but his passion for peace and his devotion to his former Padawan. And he will learn the terrible price that must be paid when keepers of the peace are forced to make war....

    For his part, Captain Spock must make the toughest decision of his Starfleet career.

    In the twenty-third century pioneers have escaped the crowded earth for life in self-sustaining orbital colonies.  One of the colonies, Rotor, has broken away from the solar system to create its own renegade utopia around an unknown red star two light-years from Earth:  a star named Nemesis.  Now a fifteen-year-old Rotorian girl has learned of the dire threat that nemesis poses to Earth's people--but she is prevented from warning them.  Soon she will realize that Nemesis endangers Rotor as well.  And so it will be up to her alone to save both Earth and Rotor as--drawn inexorably by Nemesis, the death star--they hurtle toward certain disaster.

    "You will forever be a child of two worlds, capable of choosing your own destiny. the only question you face is, which path will you choose?" The other grew up on the jagged cliffs of the harsh Vulcan desert, fighting for acceptance, for a way to reconcile the logic he was taught with the emotions he felt. In the far reaches of the galaxy, a machine of war bursts into existence in a place and time it was never meant to be. On a mission of retribution for the destruction of his planet, its half-mad captain seeks the death of every intelligent being, and the annihilation of every civilized world. Kirk and Spock, two completely different and unyielding personalities, must find a way to lead the only crew, aboard the only ship, that canstop him. "The wait is over."

    Augustine equate nothingness with the Devil? What tortuous means did 17th-century scientists employ in their attempts to create a vacuum? And why do contemporary quantum physicists believe that the void is actually seething with subatomic activity? You’ll find the answers in this dizzyingly erudite and elegantly explained book by the English cosmologist John D. Barrow.Ranging through mathematics, theology, philosophy, literature, particle physics, and cosmology, The Book of Nothing explores the enduring hold that vacuity has exercised on the human imagination. Combining high-wire speculation with a wealth of reference that takes in Freddy Mercury and Shakespeare alongside Isaac Newton, Albert Einstein, and Stephen Hawking, the result is a fascinating excursion to the vanishing point of our knowledge.

    the desperate, take-no-prisoners struggle that led humanity to Halo--the fall of the planet Reach. Now, brought to life for the first time, here is the full story of that glorious, doomed conflict.While the brutal Covenant juggernaut sweeps inexorably through space, intent on wiping out humankind, only one stronghold remains--the planet Reach. Practically on Earth's doorstep, it is the last military fortress to defy the onslaught. But the personnel here have another, higher priority: to prevent the Covenant from discovering the location of Earth.Outnumbered and outgunned, the soldiers seem to have little chance against the Covenant, but Reach holds a closely guarded secret. It is the training ground for the very first "super soldiers." Code-named SPARTANs, these highly advanced warriors, specially bioengineered and technologically augmented, are the best in the universe--quiet, professional, and deadly.Now, as the ferocious Covenant attack begins, a handful of SPARTANs stand ready to wage ultimate war. They will kill, they will be destroyed, but they will never surrender. And at least one of them--the SPARTAN known as Master Chief--will live to fight another day on a mysterious and ancient, artificial world called Halo...

    The Universe, of course, is our own. And Roundworld is Earth. As the wizards watch their accidental creation grow, we follow the story of our universe from the primal singularity of the Big Bang to the Internet and beyond. Through this original Terry Pratchett story (with intervening chapters from Cohen and Stewart) we discover how puny and insignificant individual lives are against a cosmic backdrop of creation and disaster. Yet, paradoxically, we see how the richness of a universe based on rules, has led to a complex world and at least one species that tried to get a grip of what was going on.

    Anderson. Working from Frank Herbert's own notes, the acclaimed authors reveal the chapter of the Dune saga most eagerly anticipated by readers: the Butlerian Jihad.Throughout the Dune novels, Frank Herbert frequently referred to the war in which humans wrested their freedom from "thinking machines." In Dune: The Butlerian Jihad, Brian Herbert and Kevin J. Anderson bring to life the story of that war, a tale previously seen only in tantalizing hints and clues. Finally, we see how Serena Butler's passionate grief ignites the struggle that will liberate humans from their machine masters; here is the amazing tale of the Zensunni Wanderers, who escape bondage to flee to the desert world where they will declare themselves the Free Men of Dune. And here is the backward, nearly forgotten planet of Arrakis, where traders have discovered the remarkable properties of the spice melange....

    It is so important that it provides the fundamental underpinning of all modern sciences. Without it, we'd have no nuclear power or nuclear bombs, no lasers, no TV, no computers, no science of molecular biology, no understanding of DNA, no genetic engineering—at all. John Gribbin tells the complete story of quantum mechanics, a truth far stranger than any fiction. He takes us step-by-step into an ever more bizarre and fascinating place—requiring only that we approach it with an open mind. He introduces the scientists who developed quantum theory. He investigates the atom, radiation, time travel, the birth of the universe, superconductors and life itself. And in a world full of its own delights, mysteries and surprises, he searches for Schrödinger's Cat—a search for quantum reality—as he brings every reader to a clear understanding of the most important area of scientific study today—quantum physics.

      In the past few years, a handful of scientists have been in a race to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is completely unknown.   Richard Panek tells the dramatic story of how scientists reached this conclusion, and what they’re doing to find this "dark" matter and an even more bizarre substance called dark energy. Based on in-depth, on-site reporting and hundreds of interviews—with everyone from Berkeley’s feisty Saul Perlmutter and Johns Hopkins’s meticulous Adam Riess to the quietly revolutionary Vera Rubin—the book offers an intimate portrait of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fueled their search, redefined science, and reinvented the universe.

    He provides readers with non-trivial insights into research fields they may not have encountered previously . . . I think everyone who has ever considered the possibility that other intelligent civilizations exist elsewhere within our galaxy will enjoy Where Is Everybody? They will find much to agree with, and much to argue about, in this very accessible volume.� �SCIENCE During a Los Alamos lunchtime conversation that took place more than 50 years ago, four world-class scientists agreed, given the size and age of the Universe, that advanced extraterrestrial civilizations simply had to exist. The sheer numbers demanded it. But one of the four, the renowned physicist and back-of-the-envelope calculator Enrico Fermi, asked the telling question: If the extraterrestrial life proposition is true, he wondered, "Where IS everybody?" In this lively and thought-provoking book, Stephen Webb presents a detailed discussion of the 50 most cogent and intriguing answers to Fermi's famous question, divided into three distinct groups: - Aliens are already here among us. Here are answers ranging from Leo Szilard's suggestion that they are already here, and we know them as Hungarians, to the theorists who claim that aliens built Stonehenge and the Easter Island statues. - Aliens exist, but have not yet communicated. The theories in this camp range widely, from those who believe we simply don't have the technologies to receive their signals, to those who believe the enormities of space and time work against communication, to those who believe they're hiding from us. - Aliens do not exist. Here are the doubters' arguments, from the Rare Earth theory to the author's own closely argued and cogently stated skepticism. The proposed solutions run the gamut from the crackpot to the highly serious, but all deserve our consideration. The varieties of arguments -- from first-rate scientists, philosophers and historians, and science fiction authors -- turn out to be astonishing, entertaining, and vigorous intellectual exercises for any reader interested in science and the sheer pleasure of speculative thinking. Stephen Webb is a physicist working at the Open University in England and the author of Measuring the Universe.
