Darkover: First Contact by Marion Zimmer Bradley

they’re chock full of every vitamin we know on Earth and a couple we don’t! I know, I tell you!”
    He caught Ewen’s eye, and the young doctor, a curious awareness growing in him, said slowly, “Yes. Yes, you do know, of course they’re good. Just as those mushrooms—” he pointed to a grayish fungus growing on the tree, “are wholesome and full of protein, but those—” he pointed to an exquisitely-colored golden nut, “are deadly, two bites will give you a hell of a bellyache and half a cup will kill you—how the hell do I know all this?” He rubbed his forehead, feeling the odd itch through it all, and took a fruit from Heather.
    “Here, we’ll all be crazy together then. Marvelous! Better than rations any day . . . where’s Judy?”
    “She’s all right,” MacLeod said, laughing. “I’m going off and look for some more fruits!”
     
    Marco Zabal lay alone in the shelter-tent, eyes closed, half-dreaming through closed lids of the sun on the Basque hills of his childhood. Far away in the forest it seemed that he heard singing, singing which seemed to go on, and on, high and clear and sweet. He got to his feet, not stopping to draw any garment about him, disregarding the warning pounding of his heart. An incredible glow of well-being and beauty seemed to surge through him. The sunlight was brilliant on the sloping clearing, the trees seemed to hang darkly and protectively like a beckoning roof, the flowers seemed to sparkle and glitter with a brilliance that was like gold, orange, blue; colors he had never seen before danced and sparkled before his eyes.
    Deep in the forest came the sound of singing, high, shrill, unbelievably sweet; the pipes of Pan, the lyre of Orpheus, the call of the sirens. He felt his weakness fade; his youth restored.
    Across the clearing he saw three of his companions, lying on the grass laughing, the girl kicking flowers into the air with her bare toes. He stood enraptured, watching her, entangled for a moment in the webs of her fantasy . . . I am a woman made of flowers . . . but the far-off singing lured him on; they beckoned him to join them, but he smiled, blew the girl a kiss, and bounded like a young man into the forest.
    Far ahead he saw the gleam of white—a bird? A naked body?—he never knew how far he ran, hardly feeling the rapid pounding of his heart, wrapped in the glorious euphoria of freedom from pain, following the white gleam of the distant figure—or bird?—calling out in mingled rapture and anguish, “Wait, wait—”
    The song shrilled and seemed to fill his whole head and heart. Gently, without pain, he fell into the long sweet-scented grass. The singing went on, and on, and he saw bending over him a fair face, long colorless hair waving around her eyes, a voice too sweet, too heart-wrenchingly sweet to be human, and hair turned to silver by the sun slanting through the trees, and he went happily, joyously down into darkness with the woman’s face, sweet and mad, imprinted on his dying eyes.
     
    Rafe ran through the forest, his heart pounding, slipping and falling on the steep path. He shouted, as he ran, “Camilla! Camilla!”
    What had happened? One moment she was at peace in his arms—then pure terror had surged across her face and she had screamed and begun babbling something about faces on the heights, faces in the clouds, wide-open spaces waiting to fall on her and crush her, and the next moment she had wrenched away from him and dashed away between the trees, screaming wildly.
    The trees seemed to waver and dip before his eyes, to form long black witch-claws to entangle him, tripping him up, throwing him full length into briars that raked along his arm and stung like fire. Lightning flashed with the color of the pain in his arm; he felt a wild and sudden terror as some unknown animal crashed a path in the forest, a stampede, hoofs, beating, beating, crushing him . . . he flung his arms around the bole of a tree and clung to it, the pounding
