"You are fighting time itself, and time takes no prisoners."
When a dark energy invades the galaxy, Michael Blayne and his wife, Kate Weston, are among the few unaffected by the malevolent force. Nearly everyone else, including their parents, friends and all the powerful scienticians they know, falls victim to the darkness. Even Time's Edge itself, the mysterious realm that governs the galaxy, has not escaped the dark forces.
Michael knows he must go to Time's Edge and search through the infinite realm for a way to battle the dark energy. Kate, however, has foreseen that he, too, will fall to the darkness.
