Since Molly and Hannah’s mother died they’ve been handling it as best they could. Their father, however, has not been handling it well. Not a jot. So distraught is he by the loss of his wife, in fact, that he sends his two daughters off to live with their grandparents in the country. One night Molly is witness to a frightening vision of a man run down by a pack of dogs and a horned man on a horse. In the ensuing days she tries to tell others, to no avail, then discovers the man in a nearby shed. She cannot nurse or help him, but she can learn as much as she can about him and what exactly he is. As she does, her father is drawn more and more into her life with her sister, though it takes him many tries and many mistakes before any progress can be made. The return of her father and the eventual destruction of the man come together in such a way as to give rise to winter, and the ensuing, beautiful, spring.
