The Reality Dysfunction (Night's Dawn, #1)

by Peter F. Hamilton

At that moment they were precisely thirty-six and a half light-years from their G3 home star, Garissa. If they had trained the Beezling’s remaining optical sensors on the faint diamond of light far behind, and if those sensors possessed sufficient resolution, then in thirty-six years, six months, and two days they would have seen a brief surge in the apparent magnitude as Omuta’s mercenary ships dropped fifteen antimatter planet-buster bombs on their home world. Each one had a megatonnage blast equivalent to the asteroid impact which wiped out the dinosaurs on Earth. Garissa’s atmosphere was ruined beyond redemption. Superstorms arose which would rage for millennia to come. By themselves, they weren’t fatal. On Earth, the shielded arcologies had sheltered people from their heat-wrecked climate for five and a half centuries. But unlike an asteroid impact, where the energy release was purely thermal, the planet-busters each emitted the same amount of radiation as a small solar flare. Within eight hours, the rampaging storms had spread the nuclear fallout right across the planet, rendering it completely uninhabitable. Total sterilization took a further two months.
