seconds subjective to go.

      He worked for a time trying to get a clearer look at the objective. The visual image was blurred, grainy, and heavily pixilated, but he could make out the planet, Eta Boötis IV, sectioned off by green lines of longitude and latitude, the shapes of continents roughed in. Fifteen red blips hung in space about the globe, most so close they appeared to be just skimming the globe’s surface, and he could see their motions, second to second, as the AI updated their locations. A white blip on the surface marked the objective—General Gorman’s slender beachhead. It was on the side of the planet facing Gray at the moment, the planet’s night side, away from the local sun, but in another two hours objective, it would be right on the planet’s limb—local dawn.

      Additional red blips flicked on, a cloud of them, indistinct and uncertain, centered around and over Gorman’s position. Those marked enemy targets for which there was no orbital data and that most likely were actively attacking the Marine perimeter. Or rather, they had been 136 minutes ago, when the photons revealing their positions had left Eta Boötis IV. For all Gray knew, the perimeter had collapsed hours ago, and the squadron was about to make a useless demonstration at best, fly into a trap at worst. He shoved the thought aside. They were committed, had been committed since boosting clear of the America. They would know the worst in another few subjective minutes.

      He opened his fighter’s library, calling up the ephemeris for Eta Boötis and its planets. He scrolled quickly through the star data, then slowed when he reached the entry for the fourth planet.

      PLANET: Eta Boötis IV

      Gray broke off reading at that point, shaking his head. The squadron had been briefed on the native life forms on Haris, but he’d bleeped past the recorded lectures. He wouldn’t be on the planet long enough to worry about any native life forms.

      Hell, from what he had picked up at the briefing, it was mildly bizarre that there was any life on the rock at all. One point seven billion years ago, the stellar companion of Eta Boötis had burned up its hydrogen fuel stores and entered a red giant phase before collapsing to its current white dwarf state. Planet IV had probably formed farther out than its current orbit within the star’s habitable zone, but migrated in closer as friction with the outer layers of the red giant’s atmosphere both baked it dry and slowed it down. The current ecosystem could not have even begun evolving until about a billion years ago … an impossibly short time by cosmological standards.

      Whatever was growing on Haris’s surface wasn’t going to be very bright. In fact, the chances that it would find humans tasty, or even interesting, were vanishingly remote.

      Gray shrugged the news off. He was a fighter pilot, not a ground-pounding grunt. His only view of Harisian biology would be from space, which was perfect, so far as he was concerned.

      The subjective minutes ground slowly along, as objective minutes and kilometers streamed past at a breakneck gallop.

      “Deceleration in one minute, subjective,” the AI’s voice announced in Gray’s head. “Confirm A-7 strike package release command at deceleration.” It was a woman’s voice, sultry, attention-commanding.

      “Strike package release order confirmed,” Gray replied.

      Another minute crawled past. Then, “Deceleration with strike package release in five … four … three … two … one … release. Commence deceleration.”

      At the precisely calculated release point, a portion of the Starhawk’s outer hull turned liquid, flowed open, and exposed a teardrop-shaped missile nestled within. The fighter’s AI fired the missile, then triggered the spacetime-twisting immensity of the drive singularity, this time astern, off the Starhawk’s spiked tail. At fifty thousand gravities, the Starhawk began slowing; the strike package pod kept accelerating and, from the gravfighter’s perspective, flashed forward at five hundred kilometers per second squared, the dustcatcher winking out just long enough for the teardrop to flash past unimpeded, before switching on once more.

      Ten seconds later, the gravfighter’s velocity had slowed by five thousand kilometers per second. After a minute, he was down to .87 of the speed of light, and his velocity continued to decrease.

      Six hundred thousand kilometers ahead, the strike package, still accelerating and moving at better than .997 c, began to deploy.

      At this point on the timeline, the Turusch at the planet half an AU up ahead would still be unaware that the Confederation task force had even arrived.

      They were in for one hell of a surprise.

       Tactician Emphatic Blossom at Dawn

      Enforcer Radiant Severing

       1241 hours, TFT

      Emphatic Blossom at Dawn had been named for a species of hydrogen floater on the homeworld that stunned its prey with an electric charge fired through trailing, gelatinous tentacles … emphatic indeed. It was a tactician, and a gurgled suffix on the Turusch sound-pulse translated as “tactician” carried the added meaning of a deep tactician … very roughly the equivalent of a general or an admiral in the enemy’s fleet.

      The phrase Emphatic Blossom at Dawn also implied stealth, relentless determination, and a sudden strike at the end, all qualities of mind that had contributed to its being designated a deep tactician.

      There was little stealth involved in this operation, however. The enemy was hemmed in on the planet’s surface, huddled beneath its enclosing force-bubble as Turusch particle beams and thermonuclear warheads flared and thundered. For nearly thirty g’nyuu’m now, the Turusch fleet had been hammering that shield, and it was showing signs of imminent failure.

      Victory was simply a matter of time.

      “Tactician!” a communicator throbbed from a console-shelf overhead. “Enemy ships, range twelve thousand lurm’m!”

      The news chilled … and excited. Emphatic Blossom had hoped the enemy would deploy its fleet. At that range, it would have taken light nearly five g’nyuu’m to reach the fleet’s sensors. And that meant—

      “All vessels!” the Tactician pulsed. “Disengage from the enemy! Power deep! Ships in orbit, change vector now!”

      Everything depended now on the Turusch hunterforce having the time to change course and speed. The enemy force would have launched their fighters within moments of dropping out of superluminal drive, which meant that those fighters, and any kinetic-kill devices they’d released along the way, would be just behind the light-speed wavefront bearing the news of the enemy’s arrival.
