Scientists must stop nanites from driving an asteroid into Earth in this "e;brilliantly crafted . . . edge-of-the-seat thriller"e; (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.
