The sun had long since set behind the trees of Riverside Park, on the western edge of Manhattan Island, and the lights of the New Jersey coastline were glittering on the Hudson River. Melantha Green found herself gazing at the lights, and the dark sky beyond them, as she and the two Warriors on either side of her walked along the cool grass of the upper promenade toward the stone steps leading down to the main part of the park. It had been the last sunset she would ever see, she knew, and she felt a deep sadness that it hadn't been more spectacular. But it hadn't been, and it was over.

The sky was dark, and the marginal warmth of the daylight had given way to the chill of a New York October evening. A steady northerly breeze ruffled through the last remaining leaves, and through the fear and anguish pounding in her heart she could imagine that the trees themselves were saying their farewells. Even as they settled into their yearly winter's rest, she, too, was about to settle into the quiet nothingness of death.

Except that their death would end a few months from now with the warm sunlight and the glorious renewal of spring. Her death would be forever.

The others were waiting at the top of the steps by the John Carrere Memorial as she and her escort arrived, the two small clusters of Greens and Grays standing a little apart from each other. An uneasy truce there might be right now, and genuine peace there might someday be, but that didn't mean either group particularly trusted the other. Some of the faces she could recognize in the glow from the Riverside Drive streetlights: Cyril and Aleksander, the leaders of the Greens, who had talked long and earnestly with her before this decision had been made. Her parents were there, too, trying valiantly to be stoic and loving and supportive even through the agony that was tearing their hearts apart. A couple of the Grays were familiar, too, their wide faces staring silently and emotionlessly at her from atop their squat bodies. The hope of both their peoples, they had called her, the one whose sacrifice would mean peace.

She hoped they were right. It would be a terrible thing to die for nothing.

Her escort led her to a spot midway between the two small knots of people. Cyril had a few words of greeting and encouragement, but it was clear that no one really felt like conversation, and thankfully it was soon over. With the sun down and the night growing cold, even Melantha couldn't see any point in postponing the inevitable any longer.

The preliminaries finished, Cyril and an elderly Gray with a long scar on his left cheek—Halfdan, she vaguely remembered his name—led the way down the steps into the lower part of the park, Melantha and her escort behind them, the rest of the observers joining in behind her. They walked past the small flower garden which she had been told would be her final resting spot, and she found herself wondering whether the flowers would come up extra beautiful in the spring because of it. The grass seemed springier beneath her feet than usual, though that might have been the strange shoes she'd been given to wear along with the ancient ceremonial clothing. Pinned high on her left shoulder, the unaccustomed weight of a trassk tugged uncomfortably at her dress.

They continued past the garden to the chosen spot between a pair of majestic oaks. A few more Greens were waiting there, eyeing and being eyed in turn by three more Grays silently hanging onto the side of the fifteen-foot stone wall that separated the lower part of the park from the upper promenade they'd just come from. The Gray leader beside Cyril gave a quiet order, and the Grays reluctantly came down from their perches, joining with the rest of their group. The lights of Riverside Drive blazed cheerily down from beyond the wall, and Melantha wondered briefly what would happen if some passerby stumbled upon the drama about to unfold. But most of the Humans who lived in the area were already nestled into their apartments for the night, and the wall and height differential effectively shielded them from anyone who might still be out.

She looked around her, trying to get a last taste of the world before she left it forever. The bare branches seemed to be calling to her as the wind brushed them together, and she found herself almost overwhelmed by the delicate scents of the grass and the earth and the trees themselves. Here and there above her, she could see stars peeking through the haze of the city, and even the traffic noise seemed muted tonight. It was, a small part of her mind whispered, a fitting place, and a fitting way, for a Green to die.

Even one who was only twelve years old.

The groups had shuffled into their positions for the ceremony, forming a loose circle with Melantha, her escort, and Cyril and the Gray leader in the center. "Melantha Green," Cyril said, his voice dark and solemn, "we have gathered here tonight to do that which must be done for the survival of our two peoples. Understand that what we do, we do for the best. We ask your forgiveness, and that of your family, and promise to dedicate ourselves to assuring that your sacrifice will not be in vain."

"I understand," Melantha said. As last words, she thought distantly, they were pretty pathetic. But the sadness and dread had seized her again, and how her death was remembered by others didn't seem very important. Her parents were out of her line of sight, and she thought about turning around and making sure they were still there.

But she resisted the urge. This was going to be hard enough on them without leaving a last, lingering look to ache forever in their memories.

"Thank you, Melantha," Cyril said. He took a step back, and nodded to her escort.

One of the Warriors stepped from her side and turned to face her. With his eyes carefully avoiding hers, he reached his hands up and got an almost gentle grip around her throat.

And began to squeeze.

Reflexively, she tried to twist out of his grip, her hands darting up of their own accord to grab at his wrists. But he'd been prepared for the reaction, and his adult Warrior's strength was far beyond that of a twelve-year-old girl. The blood roared in her ears, drowning out all other sounds, but in her mind she could feel the anguished calls coming from the Greens over what had to be done, even from those like Cyril who had persuaded them that it was the only way. Lancing through it all like lightning through storm clouds was the last call from her parents, a vibration of fear and pain and hopelessness.

She could feel her strength ebbing away now, her arms falling loosely to her sides, her knees starting to buckle. Vaguely, she sensed the second Warrior gripping her under her arms, supporting her so that the first could finish the job. White spots were dancing in front of her eyes, and the distant streetlight reflected on his face seemed to be fading away. Did that mean the end was near? Feeling like a dying flower wilting in his grip, she closed her eyes.

Even through the closed lids she saw the brilliant burst of light. The grip on her throat abruptly eased, and she had a vague sense of the anguish swirling around her suddenly replaced with surprise and consternation. There was a distant-sounding shout—the word Betrayal!—

The clutching hands were suddenly torn away from her throat, and she heard a gasp as something threw the Warrior to the ground. Even as she fought to suck air into her lungs, the hands that had been supporting her let go, and she felt herself collapsing toward the grass. Another arm reached out from somewhere, grabbing her around the waist. For a moment her rescuer seemed to totter; and then they were on the move, Melantha's jaw and neck bouncing painfully as he ran with her across the grass. The spots of her near-suffocation were fading away, but to her surprise she found she still couldn't see anything. The streetlights that had been blazing earlier from Riverside Drive had gone completely dark.
