Robert led the way a few feet ahead of her, using a machete to lop off the occasional branch encroaching on the narrow trail. The bright sunshine of the sun, Gimelhai, filtered softly through the forest canopy, and the spring air was warm.

Athaclena felt glad of the easy pace. With her weight redistributed from its accustomed pattern, walking was something of an adventure in itself. She wondered how human women managed to go through most of their lives with such a wide-hipped stance. Perhaps it was a sacrifice they paid for having big-headed babies, instead of giving birth early and then sensibly slipping the child into a postpartum pouch.

This experiment—subtly changing her body shape to make it seem more humanlike—was one of the more fascinating aspects of her visit to an Earth colony. She certainly could not have moved among local crowds as inconspicuously on a world of the reptiloid Soro, or the sap-ring-creatures of Jophur. And in the process she had learned a lot more about physiological control than the instructors had taught her back in school.

Still, the inconveniences were substantial, and she was considering putting an end to the experiment.

Oh, Ifni. A glyph of frustration danced at her tendril tips. Changing back at this point might be more effort than it’s worth.

There were limits to what even the ever-adaptable Tymbrimi physiology could be expected to do. Attempting too many alterations in a short time ran the risk of triggering enzyme exhaustion.

Anyway, it was a little flattering to kenn the conflicts taking shape in Robert’s mind. Athaclena wondered. Is he actually attracted to me? A year ago the very idea would have shocked her. Even Tymbrimi boys made her nervous, and Robert was an alien!

Now though, for some reason, she felt more curiosity than revulsion.

There was something almost hypnotic about the steady rocking of the pack on her back, the rhythm of soft boots on the rough trail, and the warming of leg muscles too long leashed by city streets. Here in the middle altitudes the air was warm and moist. It carried a thousand rich scents, oxygen, decaying humus, and the musty smell of human perspiration.

As Athaclena trudged, following her guide along the steep-sided ridgeline, a low rumbling could soon be heard coming from the distance ahead of them. It sounded like a rumor of great engines, or perhaps an industrial plant. The murmur faded and then returned with every switchback, just a little more forceful each time they drew near its mysterious source. Apparently Robert was relishing a surprise, so Athaclena bit back her curiosity and asked no questions.

At last, though, Robert stopped and waited at a bend in the trail. He closed his eyes, concentrating, and Athaclena thought she caught, just for a moment, the flickering traces of primitive emotion-glyph. Instead of true kenning, it brought to mind a visual image—a high, roaring fountain painted in garish, uninhibited blues and greens.

He really is getting much better, Athaclena thought. Then she joined him at the bend and gasped in surprise.

Droplets, trillions of tiny liquid lenses, sparkled in the shafts of sunlight that cut sharply through the cloud forest. The low rumble that had drawn them onward for an hour was suddenly an earthshaking growl that rattled tree limbs left and right, reverberating through the rocks and into their bones. Straight ahead a great cataract spilled over glass-smooth boulders, dashing into spume and spray in a canyon carved over persistent ages.

The falling river was an extravagance of nature, pouring forth more exuberantly than the most shameless human entertainer, prouder then any sentient poet.

It was too much to be taken in with ears and eyes alone. Athaclena’s tendrils waved, seeking, kenning, one of those moments Tymbrimi glyphcrafters sometimes spoke of—when a world seemed to join into the mesh of empathy usually reserved for living things. In a time-stretched instant, she realized that ancient Garth, wounded and crippled, could still sing.

Robert grinned. Athaclena met his gaze and smiled as well. Their hands met and joined. For a long, wordless time they stood together and watched the shimmering, ever-changing rainbows arch over nature’s percussive flood.
