Looking 50 million years into the future, this text explores the possible development or extinction of the animal world through the eyes of the time-traveller.

    Earth scientist Rocannon is on that world, and he sees his friends murdered and his spaceship destroyed. Marooned among alien peoples, he leads the battle to free this new world - and finds that legends grow around him even as he fights.

    Czerneda has earned a reputation in science fiction circles for her ability to create beautifully crafted, imaginative, yet believably realized alien races. In Survival, the first novel in her new series, Species Imperative, she draws upon this talent to build races, characters, and a universe which will draw readers into a magnificent tale of interstellar intrigue, as an Earth scientist is caught up in a terrifying interspecies conflict. Senior co-administrator of the Norcoast Salmon Research Facility, Dr. Mackenzie Connor, Mac to her friends and colleagues, was a trained biologist, whose work had definitely become her life. And working at Norcoast Base, set in an ideal location just where the Tannu River sped down the west side of the Rocky Mountains to the Pacific Coast was the perfect situation for Mac. She and fellow scientist Dr. Emily Mamani were just settling in to monitor this year's salmon runs when their research was interrupted by the unprecedented arrival of Brymn, the first member of the alien race known as the Dhryn to ever set foot on Earth.Brymn was an archaeologist, and much of his research had focused on a region of space known as the Chasm, a part of the universe that was literally dead, all of its worlds empty of any life-forms, though traces existed of the civilizations that must once have flourished in the region. Brymn had sought out Mac because she was a biologist -- a discipline strictly forbidden among his own people -- and he felt that through her expertise she might be able to help him discover what had created the Chasm. But Mac had little interest in alien races and in studies that ranged beyond Earth, and as politely as she was capable of, she tried to make it clear that she was unwilling to abandon her own work.However, the decision was soon taken out of her hands when a mysterious and devastating attack on the Base resulted in the abduction of Emily, and forced Mac to flee for her life with Brymn and the Earth special agents who were escorting him. Suddenly, it appeared that Earth itself might be under attack by the legendary race the Dhryn called the Ro, the beings they thought might be the destructive force behind the Chasm. Cut off from everything and everyone she knew, Mac found herself in grave danger and charged with the responsibility of learning everything she could that might possibly aid Earth in protecting the human race from extinction...

    The sole legacy of that war was the weapon that ended it: the death machines, the BERSERKERS. Guided by self-aware computers more intelligent than any human, these world-sized battlecraft carved a swath of death through the galaxy--until they arrived at the outskirts of the fledgling Empire of Man.These are the stories of the frail creatures who must meet this monstrous and implacable enemy--and who, by fighting it to a standstill, become the saviors of all living things.

    First published in 1984, the novel's central issues--technology, globalization, gender, sexuality, and multiculturalism--have only become more pressing with the passage of time.The novel's topic is information itself: What are the repercussions, once it has been made public, that two individuals have been found to be each other's perfect erotic object out to "point nine-nine-nine and several nines percent more"? What will it do to the individuals involved, to the city they inhabit, to their geosector, to their entire world society, especially when one is an illiterate worker, the sole survivor of a world destroyed by "cultural fugue," and the other is--you!

    Their charter was for a Class III uninhabited planet, which Zarathustra was, and it meant they owned the planet lock stock and barrel. They exploited it, developed it and reaped the huge profits from it without interference from the Colonial Government. Then Jack Holloway, a sunstone prospector, appeared on the scene with his family of Fuzzies and the passionate conviction that they were not cute animals but little people.

    Science rules the dayside of the globe. Magic rules the World of Night, and Jack of Shadows, Shadowjack the Thief, who broke the Compact and duped the Lord of High Dudgeon, walks in silence and in shadows to seek vengeance upon his enemies.

    But now, someone is eliminating the Gentian line. Campion and Purslane—two shatterlings who have fallen in love and shared forbidden experiences—must determine exactly who, or what, their enemy is, before they are wiped out of existence.

    The only problem is that the Confederacion needs him as one of its twelve Prime Operators for its secret service, the TBII. The TBII wants him as a spy, thief & assassin. It's not, of course, a problem for the Confederacion, which simply uses immersion therapy & hypnotic personality overlay for Otto's training, then sends him out in deep cover, encased in plastiflesh, on a variety of dangerous missions on a number of bizarre worlds. But for him, it's a different matter: what he has to witness & what he's forced to do take a terrible toll. Always he returns to his original self--his conscience stabbed by the memory of all those he'd killed in the service of interstellar harmony.

    He finds himself on a collision course that results in a desperate romance, and a journey into the ecstasy and dread that mirror each other at the heart of the postmodern experience.
