Mary Frewin has seen "ghosts" since she was a baby and after learning about her great-great grandmother and stumbling through a time wreck near her home in London, she understands why. There was definitely something strange about Mary Frewin. With her bright orange hair and freckles, she looked like any other child. And she tried to act like other children too, scraping through life at home and at school without calling too much attention to herself. What really separated Mary from her classmates was that she could see ghosts - red-eared ghosts. Recently, two of those forms - a thin man and his large, wolflike dog - seemed particularly interested in young Mary Frewin. In a fast-paced, well-plotted novel that explores the concept of time, Vivian Alcock has brought Mary Frewin and her red-eared ghosts vividly to life.
