"A starship crew of humans and dolphins skirts the brink of interstellar war in this epic adventure by the New York Times-bestselling author of The Postman. We are not alone. Humanity's explorations have revealed galaxies inhabited by millions of intelligent species interacting under ancient traditions. Foremost among said traditions is uplift, which requires all spacefaring races to welcome newcomers into Galactic culture by breeding and genetically guiding each client species to full sapience--but at a price. Patron races demand centuries of indentured servitude from each uplifted client. But is upstart humanity a patron or a client? The Earthship Streaker--crewed by humans and uplifted dolphins and chimpanzees--discovers a derelict armada, perhaps left by the very first patrons, the fabled Progenitors. Suddenly the Five Galaxies teeter on the brink of all-out war as fanatics hunt Streaker for the secret. With a damaged ship and hostile aliens in pursuit, the crew must band together if they hope to survive . . . This book features a new introduction by the author." --Back cover.

From one of the most critically acclaimed and well-loved authors of contemporary science fiction, a highly imaginative and exciting story as only David Brin can write . . . “High spirits and inventiveness . . . Dennis's adventures, which can only be called rollicking, are legion.”—Isaac Asimov's Science Fiction MagazinePhysicist Dennis Nuel was the first human to probe the strange realms called anomaly worlds—alternate universes where the laws of science were unpredictably changed. But the world Dennis discovered seemed almost like our own—with one perplexing difference. To his astonishment, he was hailed as a wizard and found himself fighting beside a beautiful woman with strange powers against a mysterious warlord as he struggled to solve the riddle of this baffling world.“A delightful, often very witty story, with the underlying thoughtfulness we expect from David Brin.”—Poul Anderson

Debates on the authenticity of the Star Wars franchise and the hero-or-villain status of George Lucas are at the heart of these essays by bestselling science-fiction authors. The incredible popularity of the movies has led to the formation of strong emotions within the science fiction community on the strengths and flaws of the films, exemplified here by David Brin's attacks and Matthew Woodring Stover's defense of the movies. This intense examination of the epic works addresses a broad range of issues—from politics, religion, and the saga's overall logic to the impact of the series on bookshelf space as well as science-fiction film. The question Is George Lucas a hero for bringing science fiction to a mass audience or a villain who doesn't understand the genre he's working for? is discussed before a final "Judge's Verdict" on the greatness—or weakness—of the franchise is reached.

(Well, most of them.) It seemed the galaxy was ours to lead and to share! Till we met demmies. Oh, they're not so bad. They mean well. Impulsive and exasperating, sure. Often brilliant, cheeky, moronic, volatile, always astonishing... did I mention exasperating? And lucky. Gradually, it dawned on humanity- Hey, that's what we wanted to be! In ancient sci-fi dreams, we pictured ourselves as the impulsive-lucky ones, not wise-patient elders. Only now... ... they reverently call Earthlings "the Ancient Ones." And demmies are having all the fun! Dr. Alvin Montessori is Human Advisor aboard the mostly demmie-crewed star cruiser Clever Gamble, orbiting Oxytocin 41, where something weird is going on. It starts when the crew unreels a humongous hose down to the surface... ... and their first contact team discovers a whole lot of 'something weird.'"--
