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

Though a well-regarded physicist Carl Sagan (1934-1996) is best-known as a writer of popular nonfiction and science fiction and as the host of the PBS series Cosmos . Through his writings and spoken commentary, he worked to popularize interests in astronomy, the universe, and the possibility of extraterrestrial life. From the beginning of his public career, when he co-wrote Intelligent Life in the Universe to the very end as he worked on the 1997 film adaptation of his novel Contact , these subjects absorbed him. This interest in space was rooted in his understanding of the smallness and vulnerability of humanity measured against the immense size and power of the universe. This profound philosophical humility, mixed with personal exuberance, comes through in Conversations with Carl Sagan . In interviews and profiles, Sagan discusses with verve a wide variety of topics--the environment, nuclear disarmament, religion, politics, extraterrestrial life, astronomy, physics, robotics. Whether he is discussing his science fiction or his well-researched nonfiction works, his voice embraces reason and skepticism. This volume shows how Sagan, a lifelong skeptic, refined his views and expressed amazement that Earth, for all his belief in extraterrestrial life, encompasses everything about which he cared. Tom Head of Jackson, Mississippi, is a writer and poet whose work includes Women and Families (Voices from the Civil War) , Possessions and Exorcisms (Fact or Fiction?) , and 1966 (The Turbulent 60s) .

In Harry Turtledove's The Gladiator, the Soviet Union won the Cold War. The Russians were a little smarter than they were in our own world, and the United States was a little dumber and a lot less resolute. Now, more than a century later, the world's gone Communist, and capitalism is a bad word. For Gianfranco and his friend Annarita, a couple of teenagers growing up in Milan, life in a heavily regimented, surveillance-rich command economy is just plain dreary. The eventual withering-away of the state doesn't look like it's going to happen anytime soon. Annarita's a hard-working student and a member of the Young Socialists' League. Gianfranco is a lot less motivated--but on the other hand, his father's a Party apparatchik. The biggest excitement in their lives is a wargame shop called The Gladiator, which runs tournaments, and stocks marvelous complex games you can't find anywhere else. Then, abruptly, the shop is shut down. Someone's figured out that The Gladiator's games are teaching counterrevolutionary capitalist principles. The Security Police are searching high and low for the shop's proprietors, who've not only vanished into thin air, but have left behind sets of fingerprints that aren't in the records of any government on earth. Only one staffer is left: Gianfranco and Annarita's friend Eduardo. He's on the run, and he comes to them in secret with an astonishing story: he's a time trader from our own timeline, accidentally left behind when the store was evacuated. The only way Eduardo can get home to his own timeline is if Gianfranco and Annarita can help him reach one of the other time trader sites in this world--and the Security Police will be on their tails all the way there.
