Science fiction, fantasy and ancient history join the supernatural in a young Egyptologist's quest to save a loved one at the boundaries of existence. When his young Egyptologist partner Janet vanishes during a sojourn alone in a tomb, archaeologist Wilson Ryder vows to go after her, even if it means journeying across the boundaries of existence. Ahead of Ryder and his dog lies a pre-dynastic realm of myth: the mysterious Mistress of the Bow and Ruler of Arrows, the evil Lord Seth, legions of animal-headed creatures, the venerable bird-man, the child Horus. And key to it all is the quest for the magical amulets of power. A life-and-death struggle is on at the edge of time. And the universe watches - and waits.
