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.

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.

ONCE THERE WAS MAGIC
IN THE WORLD....

Unlimited magic, enough magic for every wizard's son who ever wished to cast a spell. But the "mana," the power that makes the magic and fuels the spells, is drying up, a natural resource wasted by centuries of careless and short-sighted magicians.

In The Magic Goes Away master fantasist Larry Niven chronicled the end of an age, and the beginning of a new world where steel and muscle rule.  In this eagerly awaited sequel, Larry Niven has invited Poul Anderson, Steve Barnes, Mildred Downey Broxon, and Dean Ing into his world to tap the hidden reserves of mana and uncover the forgotten places of power.  All is not lost.  The magic may return.

THE MAGIC MAY
