She suddenly knew that she didn’t have time. She should have run when she first heard it.

Madeline turned and leapt away from the river, the weight of her backpack slamming against her back as she ran, thump, thump, thump.

And then the rumble became a roar, the roar a deafening cacophony of thunder, and in her peripheral vision Madeline saw a wall of water rising up at the top the waterfall, a tremendous wave of white turbulence. And she saw trees in the whiteness, their skeletal roots writhing in the tumult, like gigantic, fleshless hands, flexing and grabbing the air.

Madeline ran, muscles burning with the effort.

She tore across the mountainside, not going down, but going up and across, thinking the water would be less likely to reach her there. If one of those trees hit her in the head, she’d never survive. The air was burning in her lungs now, veins standing out on her neck as she struggled against the weight of her pack that wanted to pull her back.

She thought of dumping it, but there wasn’t time. Madeline raced on, trying not to think about the weight or the crashing water, trying just to flee.

And then the water hit her.

With tremendous force she smashed face-first toward the ground, but before the rocks there could cut her, she was swept off her feet in a torrent of water, tumbling and twisting and going under. Her nose filled with water, and she gasped for breath as her head went down into the frigid torrent. The fierce current whipped her around mercilessly, as if she weighed no more than a leaf.

As Madeline struggled to right herself beneath the water, her feet tangled in something hard and unyielding with a million fingers that snaked out to grab her. Rough wood and branches cut into her legs and arms, and she realized it was a tree, rolling in the current beneath her.
