The Goliath Stone

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?
