Roman nodded. So far he’d passed up any snide comments on the demise of Ferrol’s side of the dust sweat argument. Not that anyone on the bridge really needed reminding. “Sounds like a buildup of fatigue wastes,” he suggested.

“Dr. Tenzing says that’s one of the possibilities.”

“Mm. Well, we’ll just have to wait and see how fast it clears up.”

“Yes, sir. So what’s this perasiata scam, anyway?”

“It’s hardly a scam,” Roman said, his voice a little stiff. “It’s a kind of withdrawal of consciousness the space horses sometimes experience. Something like the way the Tampies sleep, or so they’ve described it.”

Ferrol nodded to himself. So there was a limit to how hard you could push a space horse. Interesting. Even more interesting that no one had discovered it before now.

“Captain?” MacKaig spoke up. “Hhom-jee signals we’re finally ready to Jump.”

“Very good. Execute.”

The words were barely out of Roman’s mouth when the sunlight did its abrupt and instantaneous change… and they were there.

To the naked eye, 1148 was merely a bright reddish star; seen through Amity’s sunscope, it was a truly awesome sight. Shrouded in a brightly lit haze, seemingly meshed together by roiling tendrils of colored vapor, the twin stars seemed to project both the ultimate in unity and the ultimate in conflict. A child in its mother’s arms; or two fighters literally tearing the life from each other.

With a shiver, Ferrol forced the images down. The last thing he needed going into a pre-nova system was an overactive imagination.

“Interesting view,” Roman remarked from behind him. “Ensign, do we have Shadrach on the scope yet?”

“Yes, sir,” MacKaig told him. “About three degrees off a direct line to the stars, range approximately forty million kilometers.”

“About as close as we were likely to get,” Roman said. “Good job. Feed the numbers to Hhom-jee and have him get us going.” He tapped his intercom, indicating to Ferrol to join the circuit. “Dr. Tenzing? Have your people come up with any theories as to what’s going on out there?”

“Guesses only at this stage, Captain,” Tenzing grunted. The scientist’s expression, Ferrol thought, seemed to be hovering midway between scientific eagerness and a very unscientific desire to be several light-years away. “Two things seem pretty certain, though. One: both stars, especially B—the dwarf—are much hotter than they should be; and two, B is also cooling down fairly rapidly. That suggests we’re looking at some variant of a classical Anselm Cycle, either gravitationally or thermally driven.”

“The Anselm Cycle being…?”

“Well, it’s never actually been observed, as far as I know, but the scenerio goes something like this. Some of the gas envelope material from A—the giant—falls past the gravitational equipoint onto B and triggers a burst of energy, which both heats B’s surface and blows off a shell of material. The extra radiant energy from that burp heats up A slightly, causing it to expand a bit more and therefore dump even more material onto B. Eventually—or so the theory goes—one of these cycles will dump enough matter onto B to trigger a proton-proton nuclear reaction in the surface. At that point, B goes nova, increases its brightness a factor of fifty thousand or so, and fries everything in the system.”

Roman seemed to digest that. “Seems reasonable enough. When can we expect the next of these burps?”

“We don’t know,” Tenzing admitted. “Best estimate is that the last one happened sixty to eighty hours ago, which turns out to be roughly two-thirds of what the theory would predict for the cycle. That would indicate the next one should come within thirty or forty hours, but I really can’t say for certain.”

“How much warning will it give us before it goes?”

Tenzing’s eyes flicked to the side. “Again, none of my people can say for certain.

Probably a few minutes at the most.”

“I see. Any idea as to which of these burps will trigger the nova itself?”

Tenzing’s face tightened. “Not really. We don’t have the equipment to take accurate readings on the plasma dynamics going on out there, and without a better feel for the Lagrange surfaces and expansion coefficients all we can really do is guess. It could go on the very next burp, or it could hold off for a couple of weeks.”

Roman nodded grimly. “Thank you, Doctor,” he said. Cutting the circuit, he swiveled to face the engineering monitor. “How’s the ship taking this?”

“Hull temperature’s going up, but not dangerously,” the ensign manning the station reported. Dangerous or not, he wasn’t taking his eyes off the readouts. “As long as B continues to cool down we should be all right. Particle radiation is marginal, but within safety limits.”

Which was all right, Ferrol knew. Spaceship hulls were built to take a lot of that kind of abuse; and if worse came to worse they could move into Pegasus’

shadow—

He spun around to face Roman; and in the captain’s face he could see that they’d both caught it at the same time. Roman got to the intercom first. “Rrin-saa? This is the captain. Why aren’t we moving?”

Ferrol keyed himself into the circuit, and for a long moment the display remained blank. Then, abruptly, it cleared to show a contact-helmeted Tampy wearing a green/purple neckerchief. “Rro-maa, yes,” he grated.

“Hhom-jee, why aren’t we moving?” Roman demanded again. “Ensign MacKaig sent you the direction several minutes ago.”

“Pegasunninni will not move.”

Roman swore under his breath. “Hhom-jee, we have got to get in there. Is Pegasus worried about getting closer to the hot star?—if so, we may be able to shield it from—”

“Pegasunninni is not worried about star,” Hhom-jee said. “He will not move. Any direction. He does not seem to be well.”

Roman looked up at Ferrol, his eyes abruptly tight… and Ferrol felt his stomach twist into a hard knot. Without Pegasus, Amity was trapped in this system.

With a star preparing itself to explode.

It was odd, Roman thought distantly. Over the years he’d spent hours on end in cramped deep-space shuttlecraft and powered worksuits, all without the slightest hint of trouble. Now, with billions of cubic kilometers of open space around him, he was suddenly feeling the unpleasant stirrings of claustrophobia.

Trapped in a pre-nova system… “What do you mean, he’s not well?” he demanded.

“You mean he’s sick, or fatigued, or what?”

“I do not know,” was the all-too predictable reply. “I know that I have never seen a space horse like this; that is all.”

Roman gritted his teeth. “Where’s Sso-ngu? Let me talk to him.”

“He is resting.”

“Well, wake him up,” Ferrol growled.

“He cannot be disturbed,” Hhom-jee said.

Ferrol started to say something else, stopped as Roman threw him a warning look.

“I’m coming down there,” he told Hhom-jee. “Keep trying.”

He broke the connection and unstrapped. “Commander, light a small fire under Tenzing’s people,” he ordered over his shoulder as he launched himself toward the door. “I want their best guess as to what’s wrong with Pegasus, and some suggestions on how to cure it, by the time I get back.”

“Yes, sir,” Ferrol called after him.

The Tampy section looked the same as it had the first time Roman had gone there, but this time he hardly even noticed the alien beauty of it. Fingers searching out the handholds half-buried in the moss, he pulled himself along the corridors as quickly as he could.

He reached the Handler room door and pushed himself through the opening, to find three of the aliens waiting quietly there for him. Though to be more accurate, only Rrin-saa and Hhom-jee were actually waiting for him: floating alone over in a far corner, humming dreamily to himself, Sso-ngu wasn’t in any shape to be expecting Roman or anyone else.
