Fourteen science fiction stories of yesterday, today, and tomorrow from a six-time winner of the Hugo Award. Frontiers can be found in all directions. Frontiers of time and space, as well as frontiers of courage, devotion, love, hate, and the outer limits of the human spirit. This outstanding collection of stories by one of science fiction's premier talents spans the length and breadth of history and the universe, while exploring thought-provoking new ideas and dilemmas. From the Baghdad of the Arabian Nights to a vast interstellar empire thousands of years in the future, from the Vatican to a one-man vessel drifting in the vast emptiness of the Asteroid Belt, from virtual reality duels to the subtle intricacies of time travel and a golf tournament on the Moon, here are tales of scoundrels and heroes, scientists and explorers, aliens and artificial intelligences, and even a young Albert Einstein. Each of them stands at the border of a new frontier and must venture out into unexplored territory—thanks to the limitless imagination of Ben Bova. "A whole tray full of treats." —Booklist "Bova proves himself equal to the task of showing how adversity can temper character in unforeseen ways." —The New York Times "Bova gets better and better, combining plausible science with increasingly complex fiction." —Los Angeles Daily News "[Bova's] excellence at combining hard science with believable characters and an attention-grabbing plot makes him one of the genre's most accessible and entertaining storytellers." —Library Journal
