What is deja vu? Is it simply a sense that something has already happened? Or does it mean that some plan is in motion? And what would it mean if life came to seem like a constant deja vu? Would this imply that free will is an illusion? Don Pierce is a scientist who values gritty experiment over beautiful theory and sees no worth in pretty stories about the meaning of things. Yet the closed egg of his life cracks open and frees him. On a business trip to Australia, Don begins to see visions of the Aboriginal Dreamtime. He is compelled to accept that visions can have overwhelming force - and that the past pervades the present."
