BOOK TWO IN THE CLASSIC HEOROT SERIES FROM GENRE LEGENDS LARRY NIVEN, JERRY POURNELLE, AND STEVEN BARNES.

Some twenty years have passed since the passengers and crew of the starship Geographic established a colony on the hostile alien world of Avalon. In that time, a new generation has grown up in the peace and serenity of the island paradise of Camelot, ignorant of the Great Grendel Wars fought between their parents and grandparents and the monstrous inhabitants of Avalon.

Now, under the influence of a charismatic leader, a group of young rebels makes for the mainland, intent on establishing their own colony, sure that they can vanquish any foe that should stand in their way.

But they will soon discover that Avalon holds darker secrets still.

At the publisher's request, this title is sold without DRM (Digital Rights Management).

Eighteen years in the making - here at last is the sequel to one of the most acclaimed science fiction novels of our time, THE MOTE IN GOD'S EYE.

Robert Heinlein called it "possibly the finest science fiction novel I have ever read."  The San Francisco Chronicle declared that "as science fiction, The Mote in God's Eye is one of the most important novels ever published."  Now Larry Niven and Jerry Pournelle, award-winning authors of such bestsellers as Footfall and The Legacy of Heorot return us to the Mote, and to the universe of Kevin Renner and Horace Bury, of Rod Blaine and Sally Fowler.

There, twenty-five years have passed since humanity quarantined the mysterious aliens known as Moties within the confines of their own solar system.  They have spent a quarter century analyzing and agonizing over the deadly threat posed by the only aliens mankind has ever encountered - a race divided into distinct biological forms, each serving a different function.  Master.  Mediator.  Engineer.  Warrior.  Each supremely adapted to its task, yet doomed by millions of years of evolution to an inescapable fate.  For the Moties must breed - or die.

And now the fragile wall separating them and the galaxy beyond is beginning to crumble.

BOOK ONE IN THE CLASSIC HEOROT SERIES FROM GENRE LEGENDS LARRY NIVEN, JERRY POURNELLE, AND STEVEN BARNES

The two hundred colonists on board the Geographic have spent a century in cold sleep to arrive here: Avalon, a lush, verdant planet lightyears from Earth. They hope to establish a permanent colony, and Avalon seems the perfect place. And so they set about planting and building.

But their very presence has upset the ecology of Avalon. Soon an implacable predator stalks them, picking them off one by one. In order to defeat this alien enemy, they must reevaluate everything they think they know about Avalon, and uncover the planet's dark secrets.

At the publisher's request, this title is sold without DRM (Digital Rights Management).

THE LUCKY ONES WENT FIRST...

The gigantic comet had slammed into Earth, forging earthquakes a thousand times too powerful to measure on the Richter scale, tidal waves thousands of feet high. Cities were turned into oceans; oceans turned into steam. It was the beginning of a new Ice Age and the end of civilization.

But for the terrified men and women chance had saved, it was also the dawn of a new struggle for survival--a struggle more dangerous and challenging than any they had ever known....

"The first satisfying end-of-the-world novel in years... and ultimate one.... masively entertaining."
CLEVELAND PLAIN-DWELLER

"Take your earthquakes, waterlogged condominiums, swarms of bugs, colliding airplanes and flaming what-nots, wrap them up and they wouldn't match one page of Lucifer's Hammer for sweaty-palmed suspense."
CHICAGO DAILY NEWS

A black hole in space.  And piercing through, a beam of ruby light brighter than a hundred moons.  Was it the eye on the face of God, or the blood red-sun of our first intergalactic visitors?

"Possibly the finest science fiction novel I have ever read."
- Robert Heinlein

"One of the most engrossing tales I've read in years."
- Theodore Sturgeon
