From the author of Jurassic Park, Timeline, and Congo comes a psychological thriller about a group of scientists who investigate a spaceship discovered on the ocean floor. In the middle of the South Pacific, a thousand feet below the surface, a huge vessel is unearthed. Rushed to the scene is a team of American scientists who descend together into the depths to investigate the astonishing discovery. What they find defies their imaginations and mocks their attempts at logical explanation. It is a spaceship, but apparently it is undamaged by its fall from the sky. And, most startling, it appears to be at least three hundred years old, containing a terrifying and destructive force that must be controlled at all costs.

Much may be gathered, indirectly, from the arguments in these pages, as to the real nature of the Earth on which we live and of the heavenly bodies which were created for us. The reader is requested to be patient in this matter and not expect a whole flood of light to burst in upon him at once, through the dense clouds of opposition and prejudice which hang all around. Old ideas have to be gotten rid of, by some people, before they can entertain the new; and this will especially be the case in the matter of the Sun, about which we are taught, by Mr. Proctor, as follows: “The globe of the Sun is so much larger than that of the Earth that no less than 1,250,000 globes as large as the Earth would be wanted to make up together a globe as large as the Sun.” Whereas, we know that, as it is demonstrated that the Sun moves round over the Earth, its size is proportionately less. We can then easily understand that Day and Night, and the Seasons are brought about by his daily circuits round in a course concentric with the North, diminishing in their extent to the end of June, and increasing until the end of December, the equatorial region being the area covered by the Sun’s mean motion. If, then, these pages serve but to arouse the spirit of enquiry, the author will be satisfied.
