“Shadows of Eternity is a novel set two centuries from now. Humanity has established a SETI library on the moon to decipher and interpret the many messages from alien societies we have discovered. The most intriguing messages are from complete artificial intelligences. Ruth, a beginner Librarian, must talk to alien minds—who have aggressive agendas of their own. She opens doors into strangeness beyond imagination—and in her quest for understanding nearly gets killed doing it. Gregory Benford is one of science fiction’s iconic writers, having been nominated for four Hugo Awards and twelve Nebula Awards. Shadows of Eternity marks Gregory Benford’s return to the sweeping galactic science fiction that readers have been waiting for.” — Provided by publisher.
