Communist China, Japan, Nazi Germany, the United States: they began World War II as mortal enemies. But suddenly their only hope for survival--never mind victory--was to unite to stop a mighty foe--one whose frightening technology appeared invincible.

Far worse beings than the Nazis were loose. From Warsaw to Moscow to China's enemy-occupied Forbidden City, the nations of the world had been forced into an uneasy alliance since humanity began its struggle against overwhelming odds. In Britain and Germany, where the banshee wail of hostile jets screamed across the land, caches of once-forbidden weapons were unearthed, and unthinkable tactics were employed against the enemy. Brilliantly innovative military strategists confronted challenges unprecedented in the history of warfare.

Even as lack of fuel forced people back to horse and carriage, physicists worked feverishly to create the first atomic bombs--with horrifying results. City after city joined the radioactive pyre as the planet erupted in fiery ruins. Yet the crisis continued--on land, sea, and in the air--as humanity writhed in global combat. The tactics of daredevil guerrillas everywhere became increasingly ingenious against a superior foe whose desperate retaliation would grow ever more fearsome.

No one had ever put the United States, or the world, in such deadly danger. But if the carnage and annihilation ever stopped, would there be any pieces to pick up?

In Videssos the city, tribune Marcus Scaurus was bored. The legion that had been magically transported to this strange world was far away. But the Emperor's niece Alypia was near -- and willing.
When their secret trysts were betrayed, Emperor Thorisin Gavras was forced to condemn Marcus as a traitor -- but with a promise of freedom and Alypia, if he could reclaim a rebel province from a fanatic usurper, with no military aid. With only centurion Gaius Philippus, Marcus set out to try the seemingly impossible task.
But the fates conspired against them, driving them further westward, into the innermost sanctum of Videssos' great enemy Yezd -- and toward the torture chambers of the evil, deathless wizard-prince Avshar.
But behind them, without orders, the men of the legion were on the march!

NO ONE COULD STOP THEM--
NOT STALIN, NOT TOGO, NOT CHURCHILL, NOT ROOSEVELT . . .
The invaders had cut the United States virtually in half at the Mississippi, vaporized Washington, D.C., devastated much of Europe, and held large parts of the Soviet Union under their thumb.
But humanity would not give up so easily. The new world allies were ruthless at finding their foe's weaknesses and exploiting them.
Whether delivering supplies in tiny biplanes to partisans across the vast steppes of Russia, working furiously to understand the enemy's captured radar in England, or battling house to house on the streets of Chicago, humankind would never give up.
Yet no one could say when the hellish inferno of death would stop being a war of conquest and turn into a war of survival--the very survival of the planet . . .

From Pearl Harbor to panzers rolling through Paris to the Siege of Leningrad and the Battle of Midway, war seethed across the planet as the flames of destruction rose higher and hotter.
And then, suddenly, the real enemy came.
The invaders seemed unstoppable, their technology far beyond human reach. And never before had men been more divided. For Jew to unite with Nazi, American with Japanese, and Russian with German was unthinkable.
But the alternative was even worse.
As the fate of the world hung in the balance, slowly, painfully, humankind took up the shocking challenge . . .

Videssos was beset by enemies abroad and had fallen into decadence at home. But on his first night in the imperial capital, The Empires health mattered less to Krispos than finding a dry place to sleep.

Driven by crushing taxes from the farm where his family had lived -- and died -- Krispos had come to the. city seeking what fortune a good mind and a strong back could earn. He had a single goldpiece to his name -- the gift, years past, of a nomad chieftain to a ragged peasant boy. Now, though the night was raw and the inn was warm, he was loath to spend that coin, for the barbarian had claimed it carried magic.

Keep his lucky goldpiece or trade it for a warm, dry bed? Krispos tucked the coin away and stepped back into the wet streets -- all unaware that so simple a choice would lead to a world of peril and possibility...

"He's one of the finest explorers of alternate histories ever." -- Locus

As they faced one another in a duel of survival, the Roman tribune Marcus Scaurus held the spell-scribed sword of a Druid priest, and the Celtic chieftain Viridovix held a similar sword, bespelled by a rival Druid sorcerer. At the moment they touched, the two found themselves under a strange night sky where no stars were familiar and where Gaul and Rome were unknown. They were in an outpost of the embattled Empire of Videssos--in a world where magic and dark sorcery would test their skill and courage as no Roman legion had ever been tested before.

When the Viking lander on the planet Minerva was destroyed, sending back one last photo of a strange alien being, scientists on Earth were flabbergasted. And so a joint investigation was launched by the United States and the Soviet Union, the first long-distance manned space mission, and a symbol of the new peace between the two great rivals.

Humankind's first close encounter with extraterrestrials would be history in the making, and the two teams were schooled in diplomacy as well as in science. But nothing prepared them for alien war -- especially when the Americans and the Soviets found themselves on opposite sides...
