Not that there was too much danger in the lower bands. Humans routinely used the beta band, or even the gamma and delta bands, though Kanga vessels ventured as high as the delta band only when speed was of over-riding importance. But no one in his right mind hit the wall as fast and as hard as BatDiv Ninety-Two would have to in order to overhaul these Kangas. Not if they had a choice.

"Course laid in, Ma'am," Captain Onslow said tonelessly.

"Then execute, Captain," she said.

"Aye, aye, Ma'am."

Defender shuddered as her normal-space drive went suddenly to full power. It felt smooth enough, but Santander knew how dreadfully overdue for overhaul Defender was, and she spared the time for a silent prayer against drive flutter as Defender's three million tons wrapped themselves in the n-drive's space-twisting web and swung in a radical course change.

The drive surge was disorienting despite the grav compensators, and the light dots of Defender's two sister ships and their escorts followed her on the plot as the under-strength battle division swerved to pursue humanity's mortal enemies across the trackless depths of more than a single space. Mangled ions streamed astern as their massive drives wailed up to max, and the high-pitched whine of the multi-dee generators sang in their bones.

"Time to the wall?" Santander let no awareness of the state of Defender's drive color her question, and Onslow hid a wry, mental grimace of appreciation for her projected sangfroid.

"Fourteen hours, Ma'am," he replied.

"Rate of closure?"

"We should make up the absolute speed differential in about ten hours, Ma'am. If they were to maintain their present gradient, we'd need over eighty standard hours to match bands. I can't give you a realistic estimate without knowing when they're going to level out."

"I don't think they're going to," Santander said softly.

"But they'll break the gamma wall in fifty hours at this rate!"

"That's a heavy force, Captain, a long way from home and in a hell of a hurry. I think they're headed for the delta band-maybe even higher."

"But, Ma'am-they're Kangas!" Onslow protested.

"True. But they know they're losing, too. They wouldn't pull this big a force off the Line unless its mission was critical, and their current gradient is a pretty good indication of the risks they're willing to run."

"Yes, Ma'am," Onslow said finally, clearly taken aback by the whole idea.

"Run a track projection," Santander said abruptly. "I know you can't nail it down, but define a general volume for me. As soon as you can, please join Commander Miyagi, Colonel Leonovna and me in the flag briefing room. I've got a bad feeling about this."

"Aye, aye, Ma'am," Captain Onslow said. He watched his gray-haired commodore's screen blank, and his heart was cold as the vacuum beyond Defender's hull. He had served with Commodore Santander off and on for ten subjective years. He'd seen her in the screaming heart of battle and listened to her voice snapping orders while her ship bucked and jerked under the enemy's pounding, and this was the first time she had ever admitted the least uncertainty... .

Commodore Santander's eyes narrowed as Captain Onslow stepped through the briefing room hatch. He looked shaken, and she braced herself for bad news as she waved him to a chair between the two officers already at the table.

Plump, fair Commander Nicolas Miyagi was physically unprepossessing, but his deadly quick mind and a flood of nervous energy poorly suited to his appearance made him an excellent planning officer. Colonel Leonovna, however, was much more than that. Indeed, she was something of a legend in the fleet, and, at a moment like this, Santander was profoundly grateful for her presence.

Commodore Santander had never resented the colonel, but she understood why some did. Leonovna was twenty bio-years older than the commodore, but she looked a quarter of her age in her impeccable Marine uniform. The colonel would never be accused of classic beauty, but her wedge-shaped, high-cheekboned face was striking, and her bright chestnut hair and blue eyes might have been designed expressly to contrast with her space-black tunic.

Yet for all her undeniable attractiveness, Santander reminded herself, Leonovna was lethal. Her golden pilot's wings bore three tiny stars, each representing ten fighter kills, but the ribbons under those wings told the true story. They were headed by one the commodore had seen on precisely three officers during her entire career: the Solarian Grand Cross. Among other things, it entitled Colonel Leonovna to a salute from any officer who hadn't won it, regardless of rank-and, as far as Josephine Santander was concerned, that was an honor to which she was more than welcome.

But that wasn't why so many people resented-and feared-the colonel. Oh, no. Those reactions stemmed from something else entirely, for Ludmilla Leonovna was descended from the Sigma Draconis First Wave.

The commodore shook herself free of her thoughts and cocked an eyebrow at Onslow. "May I assume you have more information now, Steve?"

"Yes, Ma'am. There's still room for error, but the computers make it an Ogre, three Trollheims, and one Grendel, plus escorts. There may be a Harpy out there, too."

She nodded calmly, but her mind was anything but calm. A single Ogre was bad-almost five million tons, with the firepower to sterilize a planet-but the Trollheims were worse. Far less massive (they were actually slightly smaller than Defender), they were even more heavily armed, for they were "crewed" by servomechanisms slaved to the cyborgs humans called "Trolls." A Grendel assault transport was bad news for any planet, for it carried an entire planetary assault force of Trolls and their combat mechs, but it meant little in a deep space battle. By the same token, the possibility of a Harpy-class interceptor carrier made a bad situation very little worse, for she could be only a spectator until and unless the action translated down into the alpha or lower beta band.

But any way Santander looked at it, BatDiv Ninety-Two was out-gunned and out-massed-badly-and she was far from certain the traditional human technical advantage could balance these odds. Yet suspicion stuck in her mind like a sliver of glass. The Kangas would never have wandered this far from the desperate defense of their three remaining systems unless they were engaged in something of supreme importance to their ultracautious race.

"That's a heavy weight of metal," was all she said softly.

"Agreed," Onslow said grimly, "but there's more. Commander Tho ran that track projection for you, Ma'am; they're headed for Sol."

"Sol?" Miyagi sat straighter, his blue eyes sharp. "That's insane! Home Fleet will blow them to plasma a light-month out!"

"Will they?" Leonovna spoke for the first time, looking like a teenager in her mother's uniform as she raked chestnut hair back from her forehead. "What about their gradient, Captain? Is it holding steady?"

"No," Onslow said, "it's still rising. I've never heard of anything like it. I wouldn't have believed a Kanga multi-dee could crank out that much power if I wasn't seeing it. We're wound up to max ourselves, and we're only reducing the differential slowly."

"That's what I was afraid of." Leonovna turned back to the commodore. "Could they be looking for a Takeshita Translation, Ma'am?"

There was a moment of dead silence. Trust the colonel to say it first, Commodore Santander reflected wryly.

"The thought had crossed my mind," she admitted, and touched her com button. "Navigation," she told the computer, and Commander Tho appeared on her screen. Santander was normally a stickler for courtesy and proper military procedure, but this time she didn't even give Tho time to acknowledge her call.

"Assuming present power levels remain constant, Commander," she said without preamble, "where will our Kangas break the theta wall?"
