the story of the main protagonist, Patricia Luisa Vasquez, a brilliant mathematician who has been hand-picked to help solve the mysteries of the asteroid andd. the Russian military team sent to invade and take over the asteroid, which they call The Potato c. the American/NATO team who are exploring the asteroid, which they call The Stone b. What unfolds is a story with four parts:a. Then they discover that the seventh chamber seems to be longer than the asteroid itself, and the mystery deepens. They discover that the asteroid has been hollowed out and contains seven chambers, two of which contain large cities - one more advanced than the other. A team of scientists and engineers is sent to investigate. Called the Way, it leads to the home of humanity’s descendants, and to a conflict greater than the impending war between Earth’s superpowers over the fate of the asteroid, in “the grandest work yet” by Nebula Award–winning author Greg Bear ( Locus).Ī mysterious asteroid starts circling the Earth and Moon. But what she discovers is an even greater mystery, a tunnel that exists beyond the physical dimensions of the asteroid. To prevent this future from coming to pass, theoretical mathematician Patricia Vasquez must explore Thistledown and decipher its secret history. The people who lived there survived a nuclear holocaust that nearly rendered humanity extinct-more than a thousand years from now. Three hundred kilometers in length, it is not solid rock but a series of hollowed-out chambers housing ancient, abandoned cities of human origin, a civilization named Thistledown. In a supernova flash, the asteroid arrived and entered Earth’s orbit.

From the New York Times–bestselling author of War Dogs: A novel that “may be the best constructed hard SF epic yet” ( The Washington Post).
