Prescient and scientifically accurate, Heart of the Comet is known as one of the great hard SF novels of the 1980s.

But all too soon, native cells - that might once have brought life to Earth - begin colonizing the colonists. As factions battle over the comet's future - and that of Earth - only love, courage, and ingenuity can avert disaster and spark a new human destiny.

The Solarian League's navy counts its superdreadnoughts by the thousands. Not even its own government knows how enormous its economy truly is. And for hundreds of years, the League has borne the banner of human civilization, been the ideal to which humanity aspires in its diaspora across the galaxy. But the bureaucrats known as the "Mandarins," who rule today's League, are not the men and women who founded it so long ago. They are corrupt, venal, accountable to no one...and they've decided the upstart Star Kingdom of Manticore must be destroyed.

Jazz Bashara is a criminal. Well, sort of. Life on Artemis, the first and only city on the moon, is tough if you're not a rich tourist or an eccentric billionaire. So smuggling in the occasional harmless bit of contraband barely counts, right? Not when you've got debts to pay and your job as a porter barely covers the rent. Everything changes when Jazz sees the chance to commit the perfect crime, with a reward too lucrative to turn down.

It's all-out war. Our cities fall. Millions die. The scum, these cruel aliens from deep space, are determined to kill us all. So we must kill them. Humanity musters its greatest fleet.

Earth's fleet flies through space. We fly toward millions of enemy ships. We fly to almost certain death.

For over a hundred years, Chisholm, a Rim World colony, has produced beef for most of Human Space, raising vast herds of a breed of Giant Longhorns. Things are changing, and land reform is demanded by small ranchers and farmers, placing restrictions on the existing open range policy. The wealthy large ranchers will stop this, any way they can, to preserve their profits. Passions are high and the opposing sides have turned violent.

We colonized 700 planets. Humankind enjoyed the benefits of expansion room and the end of wars. We even disbanded our military. Then the Krall found us. The Krall have used thousands of years of combat to select the genes of the strongest and fastest warriors. They are a species determined to dominate the entire galaxy, through destruction and annihilation of every opponent.

Koban is an uninhabited high-gravity planet with impossibly fast savage animals, which employ organic superconducting nerves. This deadly world is where the Krall tested humans for war capability.

Tag, an exceptional young human living in Central City on the planet Earth, tries to keep his powerful, one-of-a-kind skills undetected by leading an ordinary life and staying under the radar. But one day, on the way home from school, Tag's compassion leads him to make a decision that alters the course of his life - and history.

Already faster and more powerful than the last 17 species that they have destroyed or subjugated, the Krall have set their sights on humankind. After testing humans on their future home world of Koban and finding them worthy opponents, the Krall start a war of slow extermination with the rest of humanity. The war is intended to last generations as they apply their own version of "natural selection" to cull their weaker warriors in combat, purifying the Krall gene pool with their finest warriors for breeding.

Spacer Buck Fryman emerges from the local lockup with a dream and a plan. He'll go into business himself, as a space freighter. He'll take the dangerous routes, sail fast without waiting for the convoys normally needed for pirate protection, and if a pirate does decide to take him on, he'll prove that he's not just a barroom brawler, he can defend himself in space as well.
