Young Hugh Tregarthen has grown up in a seafaring Cornish family, but is not born to follow the family tradition. Against his mother's wishes, he is coxswain of a lifeboat -- an important job along the treacherous coastline, which makes his mother proud, despite her misgivings. One morning, as he sets out for his boat Janet, invalid Mrs. Tregarthen warns her son of an ominous dream she had the previous night. He laughs it off... but sometimes, dreams come true. - Summary by Lynne Thompson
