The Junction was a sphere in space, a light-second in diameter. That was an enormous volume, but it seemed considerably smaller when it was threaded through with ships moving under Warshawski sail. And there were seven secondary termini now, each with its own separate but closely related inbound and outbound lanes. Even in time of war, the Junction's use rate had continued to do nothing but climb. Fifteen years ago, the traffic controllers had handled one transit every three minutes. Now they were up to over a thousand inbound and outbound transits a T-day-one transit every eighty-five seconds along one of the fourteen lanes-and an astonishing amount of that increase moved along the Manticore-Lynx lane.

As she watched, a six-million-ton freighter came through the central terminus from Lynx, rumbling down the inbound lane. One instant there was nothing-the next, a leviathan erupted out of nowhere into here. Her Warshawski sails were perfect disks, three hundred kilometers in diameter, radiating the blue glory of transit energy like blazing mirrors. Then the energy bled quickly away into nothingness, and the freighter folded her wings. Her sails reconfigured into impeller bands, and she gathered way in n-space as she accelerated out of the nexus. She was headed away from the Manticore System, for the Lynx holding area, which meant she was only passing through-like the vast majority of Junction shipping-and was probably already requesting insertion into another outbound queue.

Hexapuma moved steadily forward, and Helen watched in fascination as the azure fireflies of Warshawski sails flashed and blinked like summer lightning, pinpricks scattered across the vast sooty depths of the Junction. The nearest ones, from ships inbound from Lynx, were close enough for her to see details. The most distant ones, from ships inbound from the Gregor System, were so tiny that, even with the display's magnification, they were only a handful of extra stars. Yet she felt the vibrant, throbbing intensity of the Junction, beating like the Star Kingdom's very heart. Her father had explained to her when she was very young that the Junction was both the core of the Star Kingdom's vast wealth, and the dagger against the Star Kingdom's throat. Not so much because of the possibility of invasion through the Junction, as because of the temptation it posed to greedy neighbors. And as she looked at that unending stream of merchantships, each of them massing millions of tons, each of them paying its own share of transit duties, and probably at least a third of them carrying Manticoran transponder codes, she understood what he'd meant.

Senior Master Chief Clary held Hexapuma 's place in the queue without additional orders, and as the number under her icon dropped to "3," Terekhov glanced down into the com screen connecting him to Engineering. Ginger Lewis looked back at him, her green eyes calm.

"Commander Lewis," he said, with a tiny nod. "Stand by to reconfigure to Warshawski sail on my command, if you please."

"Aye, aye, Sir. Standing by to reconfigure to sail." Terekhov nodded again, then gave Senior Master Chief Clary's maneuvering plot a quick check. The number on it had dropped from "3" to "2" while he was speaking to Lewis, and his eyes switched briefly to the visual display as the Solarian freighter ahead of Hexapuma drifted farther forward, hesitated for just an instant, and then blinked into nothingness. The number on Clary's plot dropped to "1," and the captain turned to cock an eyebrow at Lieutenant Commander Nagchaudhuri.

"We're cleared to transit, Sir," the com officer reported after a moment.

"Very good, Commander. Extend our thanks to Junction Central," Terekhov said, and turned his chair slightly back towards Clary.

"Take us in, Helm."

"Aye, aye, Sir."

Hexapuma accelerated very slightly, moving forward under just over twenty-five gravities' acceleration as she slid flawlessly down the invisible rails of her outbound lane. Her light code flashed bright green as she settled into exact position, and Terekhov looked back at Lewis.

"Rig foresail for transit."

"Rig foresail, aye, Sir," she replied. "Rigging foresail-now."

No observer would have noticed any visible change, but the bridge displays told the tale as Hexapuma 's impeller wedge dropped abruptly to half-strength. Her forward nodes were no longer generating their part of the wedge's n-space stress bands. Instead, her beta nodes had shut down, and her alpha nodes had reconfigured to produce a Warshawski sail, a circular disk of focused gravitation that extended for over a hundred and fifty kilometers in every direction.

"Stand by to rig aftersail on my mark," Terekhov said quietly, his eyes focused on his own maneuvering plot as Hexapuma continued to creep forward under the power of her after impellers alone. A new window opened in a corner of the plot, framing numerals that flickered and changed, dancing steadily upward as the foresail moved deeper into the Junction. The Junction was like the eye of a hyper-space hurricane, an enormous gravity wave, twisting forever between widely separated normal-space locations, and the Warshawski sail caught at that unending, coiled power. It eased Hexapuma gently into its heart, through the interface where grav shear would have splintered an unprotected hull.

The dancing numbers whirled upward, and Helen felt herself tensing internally. There was a safety margin of almost fifteen seconds on either side of the critical threshold, but her imagination insisted upon dwelling on the gruesome consequences which would ensue if that window of safety were missed.

The numbers crossed the threshold. The foresail was now drawing sufficient power from the tortured grav wave spiraling endlessly through the Junction to provide movement, and Terekhov nodded slightly in satisfaction.

"Rig aftersail now, Commander Lewis," he said calmly.

"Aye, aye, Sir. Rigging aftersail now," she replied, and Hexapuma twitched. Her impeller wedge disappeared entirely, a second Warshawski sail sprang to life at the far end of her hull from the first, and a wave of queasiness assailed her entire crew.

Helen was no stranger to interstellar flight, but no one ever really adjusted to the indescribable sensation of crossing the wall between n-space and h-space, and it was worse in a junction transit, because the gradient was so much steeper. But the gradient was steeper on both sides, which at least meant it was over much more quickly.

The maneuvering display blinked again, and for an instant no one had ever been able to measure, HMS Hexapuma ceased to exist. One moment she was seven light-hours from the Star Kingdom's capital planet; the next moment, she was four light-years from a G2 star named Lynx... and just over seven light— centuries from Manticore.

"Transit complete," Senior Master Chief Clary announced.

"Thank you, Helm," Terekhov acknowledged. "That was well executed." The captain's attention was back on the sail interface readout, watching the numbers plummet even more rapidly than they had risen. "Engineering, reconfigure to impeller," he said.

"Aye, aye, Sir. Reconfiguring to impeller now."

Hexapuma 's sails folded back into a standard impeller wedge as she moved forward, accelerating steadily down the Lynx inbound lane, and Helen permitted herself a mental nod of satisfaction. The maneuver had been routine, but "routine" didn't mean "not dangerous," and Captain Terekhov had hit the transit window dead center. If he'd been off as much as a full second, either way, she hadn't noticed it, and she'd been sitting right at Lieutenant Commander Wright's elbow, with the astrogator's detailed readouts directly in front of her.

But now that transit had been completed, she found herself beginning to envy Ragnhild after all. Astrogation's maneuvering plot wasn't as good as Tactical's for displaying information on other ships, and there were a lot of other ships out there.

This terminus of the Junction was less conveniently placed than most of the others in at least one respect. The closest star, a little over five and a half light-hours from the terminus, was a planetless M8 red dwarf, useless for colonization or for providing the support base a wormhole junction terminus required. Every bit of the necessary infrastructure had to be shipped in, either direct from Manticore or from the Lynx System-sixteen hours of flight for a warship in the Zeta bands, and thirty-two hours for a merchantship in the Delta bands. That wasn't very far, as interstellar voyages went, but it was far enough that it would be difficult for anyone to make a day-trip for a few hours' visit at a planet suited to human life.

Moreover, Lynx was a Verge system, with very limited industrial infrastructure and even less modern technology. There was a distinct limit on anything except raw materials and foodstuffs which it could provide, and its labor force would have to be entirely retrained on modern hardware before it could make any significant contribution to the development and operation of the terminus.

Which didn't mean there wasn't a great deal going on, anyway. Even with the limitations of her astrogation display, as opposed to the tactical plot, Helen could see that.

Although the Star Kingdom had opted not to reactivate the fortresses around the Junction's central terminus, there were at least a dozen of them under construction at the Lynx Terminus. They wouldn't be as big as the Junction forts, but they were being shipped in in prefabricated chunks, and unlike the Junction forts, they were being built with the latest in weapons, sensors, and EW systems. And they were also being built using the same manpower-reducing automation which was a feature of the most recent Manticoran and Grayson warship designs. When finished, each would mass about ten million tons, significantly larger than any superdreadnought, and with far less internal volume devoted to impeller rooms. Bristling with missile tubes and LAC service bays, they would constitute a most emphatic statement of the Star Kingdom's ownership of the wormhole terminus.

Purely civilian installations were also under construction at a frantic rate. The mere existence of the terminus, especially in light of all of the other termini of the Manticoran Wormhole Junction, was acting on merchant shipping less like a magnet than a black hole. The Lynx Terminus cut distances-and thus time-between, say, New Tuscany and Sol from over five hundred light-years to less than two hundred and fifty. That was a savings of over twelve T-weeks for a typical freighter, and the interlocking network of the Manticoran Junction and a handful of smaller ones allowed similar time savings around almost three-quarters of the Solarian League's huge perimeter. And, Helen thought grimly, when the annexation was completed, that terminus would also move the Star Kingdom's border far around the Solarian frontier and five hundred light-years closer to places like Mesa.
