Scientists must stop nanites from driving an asteroid into Earth in this “brilliantly crafted . . . edge-of-the-seat thriller” (Kirkus Reviews, starred review). Twenty-five years ago, Doctor Toby Glyer and William Connors made a revolutionary breakthrough in nanotechnology. Their controversial nanites were capable of everything from miracle cures for the terminally ill to AI for asteroid-mining missions. But when the nanite-run Briareus mission to divert an Earth-crossing asteroid dropped out of contact soon after reaching its target, the entire program was shut down and the use of nanotechnology forcibly suppressed. Now a much, much larger asteroid is on a collision course with Earth—and the Briareus nanites may be responsible. While governments scramble to find a solution, Doctor Glyer knows that their only hope to avoid Armageddon lies in the nanites themselves. On the run, Glyer must track down Connors and find a way to make contact with their wayward children before a two-hundred-gigaton asteroid smashes into Earth. Will Glyer’s be Earth’s salvation, or destruction? Praise for The Goliath Stone “A fast read, filled with fascinating characters and mind-binding concepts. I should have worn a crash helmet.” —Larry Bond, New York Times–bestselling author of Shattered Trident “A future so brilliantly rendered that it feels shockingly real. This stunning book is Niven at the absolute top of his game, a surefire award winner and fan pleaser.” —Whitley Strieber, New York Times–bestselling author of The Grays “A rollicking good time.” —Publishers Weekly (starred review) “With witty dialogue and laugh-inducing prose, this is an incredible fun read, sure to entertain SF fans.” —Booklist

In the Retro Hugo Award–nominated novel that inspired the Syfy miniseries, alien invaders bring peace to Earth—at a grave price: “A first-rate tour de force” (The New York Times). In the near future, enormous silver spaceships appear without warning over mankind’s largest cities. They belong to the Overlords, an alien race far superior to humanity in technological development. Their purpose is to dominate Earth. Their demands, however, are surprisingly benevolent: end war, poverty, and cruelty. Their presence, rather than signaling the end of humanity, ushers in a golden age . . . or so it seems. Without conflict, human culture and progress stagnate. As the years pass, it becomes clear that the Overlords have a hidden agenda for the evolution of the human race that may not be as benevolent as it seems. “Frighteningly logical, believable, and grimly prophetic . . . Clarke is a master.” —Los Angeles Times
