The transmission ended. "I'm going to have to make my apologies. Can I call you later?" the android said. "There's an emergency in New Jersey. It seems Earth has been invaded by aliens from outer space."

"Well. If you've got to go."

"I'll call you later. I promise."

The android's shape dimmed. Ozone crackled. He rose through the ceiling.

Hiram stared, the champagne bottle in his hand. He turned to Cyndi. "Was he serious?" he asked.

"He's a nice guy, for a machine," Cyndi said, propping her chin on her hand. "But definitely a screw loose somewhere." She held out her glass. "Let's party, Hiram."

Not far away, a man lay torn by nightmare. Monsters slavered at him in his dreams. Images passed before his mind, a dead woman, an inverted pentagram, a lithe naked man with the head of a jackal. Inchoate shrieks gathered in his throat. He woke with a cry, covered in sweat.

He reached blindly to the bedside lamp and switched it on. He fumbled for his glasses. His nose was slippery with sweat and the thick, heavy spectacles slid down its length. The man didn't notice.

He thought of the telephone, then realized he'd have to maneuver himself into his wheelchair in order to reach it. There were easier ways to communicate. Within his mind he reached out into the city. He felt a sleepy mind answering inside his own.

Wake up, Hubbard, he told the other mentally, pushing his spectacles back up his nose. TIAMAT has come.

A pillar of darkness rose over Princeton. The android saw it on radar and first thought it smoke, but then realized the cloud did not drift with the wind, but was composed of thousands of living creatures circling over the landscape like a flock of scavenger birds. The pillar was alive.

There was a touch of uncertainty in the android's macroatomic heart. His programming hadn't prepared him for this.

Emergency broadcasts crackled in his mind, questioning, begging for assistance, crying in despair. Modular Man slowed, his perceptions searching the dark land below. Large infrared signatures-more Swarm buds-crawled among tree-lined streets. The signatures were scattered but their movement was purposeful, heading toward the town. It seemed as if Princeton was their rallying point. The android dropped, heard tearing noises, screams, shots. The guns on his shoulders tracked as he dipped and increased speed.

The Swarm bud was legless, moving like a snail with undulating thrusts of its slick thirty-foot body. The head was armored, with dripping sideways jaws. A pair of giant boneless arms terminated in claws. The creature was butting its head into a two-story suburban colonial, punching holes, the arms questing through windows, looking for things that lived inside. Shots were coming from the second floor. Christmas lights blinked from the edges of the roof, the ornamental shrubs.

Modular Man hovered overhead, fired a precise burst from his laser. The pulsed microwave was invisible, silent. The creature quivered, rolled on its side, began to thrash. The house shuddered to mindless blows. The android shot again. The creature trembled, lay still. The android slipped feetfirst into the window where the shots had been coming from, saw a stark-naked fat man clutching a deer rifle, a teenage boy with a target pistol, a woman clutching two young girls. The woman was screaming. The two girls were too stunned even to tremble. "Jesus Christ," the fat man said.

"I killed it," the android said. "Can you get to your car?"

"I think so," the fat man said. He stuffed rounds into his rifle. His wife was still screaming.

"Head east, toward New York," Modular man said. "They seem to be thickest around here. Maybe you can convoy with some neighbors."

"What's happening?" the man asked, slamming the bolt back and then forward. "Another wild card outbreak?"

"Monsters from space, apparently." There was a crashing sound from behind the house. The android spun, saw what looked like a serpent sixty feet long, moving in curving sidewinder pattern as it bowled down bushes, trees, power poles. The underside of the serpent's body writhed with tenfoot cilia. Modular Man sped out the window, fired another burst of microwave at the thing's head. No effect. Another burst, no success. Behind him, the deer rifle barked. The woman was still screaming. Modular Man concluded that the serpent's brain wasn't in its head. He began firing precise bursts down the length of its body.

Timbers moaned as the serpent struck the house. The building lurched from its foundations, one wall shattered, the upper story drooping dangerously. The android fired again and again. He could feel his energy running low. The deer rifle fired once more. The serpent raised its head, then drove it through the window where the fat man was firing. The serpent's body pulsed several times. Its tail thrashed. The android fired. The screaming stopped. The serpent withdrew its head and began to coil toward the next house. The android was almost drained of energy, barely retaining enough to stay airborne.

These tactics, Modular Man decided, were not working. Attempts to aid individuals would result in a scattered and largely futile effort. He should scout the enemy, discover their numbers and strategy, then find organized resistance somewhere and assist.

He began flying toward Princeton, his sensors questing, trying to gather a picture of what was happening.

Sirens were beginning to wail from below. People stumbled from broken homes. Emergency vehicles raced beneath flickering lights. A few automobiles zigzagged crazily down rubble-strewn streets. Here and there fires were breaking out, but dampness and occasional drizzle were keeping them confined. Modular Man saw a dozen more serpents, a hundred smaller predators that moved like panthers on their half-dozen legs, scores of a strange creature that looked like a leaping spider, its four-foot-wide body bounding over trees on stiltlike legs. A twenty-foot bipedal carnivore brandished teeth like a tyrannosaur: Other things, difficult to see on infrared, moved like carpets close to the ground. Something unseen fired a cloud of three-foot needles at him, but he saw it coming on radar and dodged. The cloud over Princeton was still orbiting. The android decided to investigate.

There were thousands of them, dark featherless flapping creatures like flying throw rugs. Amid the concerted roar of their wings they made low moaning noises, thrumming like bass strings. They swooped and dove, and the android understood their tactics when he saw a vehicle burst from a Princeton garage and skid down the street. A group of flappers swooped down in a group, battering at the car bodily and enfolding the target within their leathery shapes, smothering it beneath their weight. The android, his energies partially recovered, fired into the fliers, dropping a few, but the car swerved over a curb and smashed into a building. More fliers descended as the first group began to squeeze through shattered windows. Corrosive acid stained the car's finish. The android rose and began firing into the airborne mass, trying to attract their attention.

A cloud dove for him, hundreds at once, and Modular Man increased speed, bearing south, trying to lead them away, dead fliers dropping like leaves as he fired short bursts behind him. More and more of the orbiters were drawn into the pursuit. Apparently the creatures were not very intelligent. Dodging and weaving, staying just ahead of the fluttering cloud, the android soon had thousands of the fliers after him. He came up over a rise, and saw the Swarm host before him. For a moment his sensors were overwhelmed by the staggering input.

An army of creatures were advancing in a curved wave, a sharply angled crescent that pointed north to Princeton. The air was filled with grinding, rending sounds as the Swarm bulldozed its way through a town-houses, trees, office buildings, everything-leveling everything in its path. The android rose, making calculations, the fliers moaning and flapping at his back. The host was moving quickly for doing such a thorough job; the android estimated twelve to fifteen miles per hour.
