‘The Ganzer Rain Forest on Melde was deep and wide; the faintest ghost of a breeze whispered among the colossal trees, slithered through the interlocked vines, and crept broken-backed over hook-edged grass. Drops of water slid painfully down and around the tangled foliage like exhausted runners of a maze, coming to rest at last in the spongy and indifferent soil. Shadows mingled and danced, faded and reappeared , called in spurious motion by two tired suns in a mouldy green sky. Overhead, a desolate therengol whistled for his mate, and heard in reply the quick ominous cough of a predatory kingspringer. And through this dolorous woodland, so tantalisingly like Earth and yet so different, Martin Flynn moved in his unfamiliar Melden body, his eyes downcast, searching for ganzer eggs but not knowing what they looked like.’
