The narrative follows a spirited young girl known as Coppertop whose sleepless night in an old four-poster bed leads into a sequence of fanciful, episodic adventures. Imagination and personified winds carry her through thunderstorms, snowy lands, tropical isles, shipwrecks, encounters with bears, crocodiles, mist maidens, and peculiar beings such as weather clerks and a white elephant. Accompanied by imaginary companions and a cherished keepsake, she faces traps and rescues, draws on courage and resourcefulness, and discovers wonder and comfort amid peril and enchantment.
