The Corridors of Time
By Poul Anderson
The far-ranging SF adventure of the time wars that shaped earth's destiny! THE TIME WARS. Lockridge knew her as Storm. Pastward she was known as Mystery or Goddess or Koriach, depending on which gate she opened in the tunnels that pierced humankind's long childhood like spears. He served her for love, as did the others--roundhead and Celt, Druid and Junker—who fought for her in the fierce time wars that ranged from Stonehenge to Hiroshima. But his love turned to fear when he saw what the future held.
From inside front cover: Attention! This is Brann! "A Wildrunner has entered temporal transit on sub-level nine. He must be captured alive at any cost!" Lockridge twisted through the gate, falling with the shock of phase change. The fear of the mind machine brought him to his feet and onto the gravity sled, just as half a dozen men poured through the curtain after him. Stun beams splashed around him as he grabbed the acceleration control light with his palm and sped away—futureward. His heart shook him as a dog shakes a rat, and he remembered Storm seated by a fire in a wolf-haunted forest: We have seen the future, even beyond our own era. We were turned back with weapons we did not understand. We no longer try. It was too terrible. I served you, Koriach, he sobbed. Goddess, help me! He sped on through the corridor, which faded to a milky whiteness beyond sight.
