but what truly fascinated her was the tree's anti-disease defense mechanism. The unending network of branches and trunks should have made a picket wood system lethally vulnerable to diseases and parasites, but the plant had demonstrated a sort of natural quarantine process. Somehow—and Dr. Harrington had yet to discover how—a picket wood system was able to sever its links to afflicted portions of itself. Attacked by disease or parasites, the system secreted powerful cellulose-dissolving enzymes that ate away the connecting cross-branches and literally disconnected them at intervening nodal trunks, and Dr. Harrington was determined to locate the mechanism which made that possible.
But at the moment, her mother's interest in picket wood meant very little to Stephanie beside her realization of the same plant's importance to treecats. Picket wood stopped well short of the tree line, but it crossed mountains readily through valleys or at lower elevations, and it could be found in almost every climate zone. All of which meant it would provide treecats with the equivalent of aerial highways that could literally run clear across a continent! They could travel for hundreds—thousands!—of kilometers without ever once having to touch the ground where larger predators like hexapumas could get at them!
She laughed aloud at her deduction, but then her glider slipped abruptly sideways, and her laughter died as she stopped thinking about the sorts of trees beneath her and recognized instead the speed at which she was passing over them. She raised her head and looked around quickly, and a fist of ice seemed to squeeze her stomach.
The clear blue skies under which she had begun her flight still stretched away in front of her to the west. But the eastern sky
She should have seen it coming sooner, she thought numbly, hands aching as she squeezed the glider's grips in ivory-knuckled fists. She should have kept an eye out for it! But she was used to having other people—
A harder fist of wind punched at her glider, staggering it in mid-air, and fear became terror. The following wind had been growing stronger for quite some time, a small, logical part of her realized. No doubt she would have noticed despite her concentration if she hadn't been gliding in the same direction, riding in the wind rather than across or against it where the velocity shift would
But there was no time. She'd messed up, and for the first time in her life, Stephanie Harrington confronted her own mortality. All the theoretical discussions of what to do in bad weather, all the stern warnings to avoid rough air, came crashing in on her, and they were no longer theoretical. She was in deadly danger, and she knew it. Countergrav unit or no, a storm like the one racing up behind her could blot her out of the air as casually as she might have swatted a fly, and with just as deadly a result. She could die in the next few minutes, and the thought terrified her, but she didn't panic.
Yes, she had to com Mom and Daddy, but it wasn't as if she didn't know exactly what they'd tell her to do if she did. She had to get out of the air, and she couldn't afford the distraction of trying to explain where she was while she tried to get down safely . . . especially through that solid-looking green canopy below her.
She banked again, shivering with fear, eyes desperately seeking some opening, however small, and the air trembled as thunder rumbled behind her.
Climbs Quickly reared up on true-feet and hand-feet, lips wrinkling back from needle-sharp white fangs as a flood of terror crashed over him. It pounded deep into him, waking the ancient fight-or-flight instinct which, had he but known it, his kind shared with humanity, but it wasn't
It took him an instant to realize that, yet it was true. It wasn't his fear; it was the two-leg youngling's, and even as the youngling's fear ripped at him, he felt a fresh surge of wonder. He was still too far from the two- leg. He could never have felt another of the People's mind glow at this distance, and he knew it, but this two-leg's mind glow raged through him like a forest fire, screaming for his aid without even realizing it could do so, and it struck him like a lash. He shook his head once, and then flashed down the line of what humans called picket wood like a cream and gray blur while his fluffy tail streamed straight out behind him.
Desperation filled Stephanie. The thunderstorm was almost upon her—the first white pellets of hail rattled off her taut glider covering—and without the countergrav she would already have been blotted from the sky. But not even the countergrav unit could save her from the mounting turbulence much longer, and—
Her thoughts chopped off as salvation loomed suddenly before her. The black, irregular scar of an old forest fire ripped a huge hole through the trees, and she choked back a sob of gratitude as she spied it. The ground was dangerously rough for a landing in conditions like this, but it was infinitely more inviting than the solid web of branches tossing and lashing below her, and she banked towards it.
She almost made it.
Climbs Quickly ran as he'd never run before. Somehow he knew he raced against death itself, though it never occurred to him to wonder what someone his size could do for someone the size of even a two-leg youngling. It didn't matter. All that mattered was the terror, the fear—the danger—which confronted that other presence in his mind, and he ran madly towards it.

It was the strength of the wind which did it. Even then, she would have made it without the sudden downdraft that hammered her at the last instant, but between them, they were too much. Stephanie saw it coming in the moment before she struck, realized instantly what was going to happen, but there was no time to avoid it. No time even to feel the full impact of the realization before her glider crashed into the crown of the towering evergreen at over fifty kilometers per hour.

Climbs Quickly slithered to a stop, momentarily frozen in horror, but then he gasped in relief. The sudden silence in his mind wasn't—quite—absolute. His instant fear that the youngling had been killed eased, but something deeper and darker, without the same bright panic but with even greater power, replaced it. Whatever had happened, the youngling was now unconscious, yet even in its unconsciousness, he was still linked to it . . . and he felt its pain. It was injured, possibly badly—possibly badly enough that his initial fear that it had died would prove justified after all. And if it was injured, what could
But what one of the People couldn't do, many of them often
He stood irresolute, tail flicking, ears flattened as the branch beneath him creaked and swayed and the first raindrops lashed the budding leaves. Rain, he thought, a flicker of humor leaking even through his dread and uncertainty. Was it
Strangely, that thought broke his paralysis, and he shook himself. All he knew so far was that the two-leg was hurt and that he was very close to it now. He had no way of knowing how bad its injuries might actually be, nor
