This book is about a lot of things: the embodiment of winter cold as a cosmic force, the effect of an evil legacy on a family, the vicissitudes of family life, the nature of creativity and its sources, and the difficulties of trying to earn a living in the publishing world as it was when the book was published in the 1990s.
As the story opens, Ben is an eight-year-old boy, newly orphaned, who travels back on the train to his home town to visit the graveyard where his most of his family have been buried (his mother has been buried in Norwich where her sister, his aunt, lives). He has a formative experience with a lifeform which manifests as dancing snowflakes, but before he can follow it into the woods, he is intercepted by well-meaning adults and returned by the police to his aunt. A brief chapter from another POV hints that the car accident in which his parents and grandparents were killed was caused by his grandmother who had severe concerns about something happening in the family - involving her husband, son and grandson, Ben - connected with the forest near their house; a pine forest which had been planted around the oak grove where Ben's great grandfather, an explorer of the frozen north and recorder of folktales, was found dead years before. Ben's aunt finds him secretly reading his great grandfather's book at night and is so disturbed that she destroys it: the book is so rare that Ben is never able to obtain another copy.
The book then flashes forward to when Ben is an adult, and the father of two pre adolescent children. He is a writer of children's books which retell the stories from the lost book, after immersion for years in hs subconscious. His wife, Ellen, is an artist who illustrates his tales. He struggles with the attitudes of his publishing company due to a personnel change and far less enthusiasm for his books.
Ben's aunt dies and he discovers he has inherited the old family home which his aunt was in the process of trying to sell, having rented it out for years unbeknown to him. He and the family visit and become keen to take up residence. At first, all goes well and they start to find a place in the local community, but then resonances from the forest start to affect Ben, and eventually the whole town and ultimately the world is placed in jeopardy.
There is a very slow build up to this story, which I don't mind, but there is also far too much inclusion of things that go absolutely nowhere, such as the job interview which Ellen attends, where she discovers that an ex-colleague from years ago, a sexual harrasser who stole her ideas, is one of the interviewers. Ultimately, she decides to turn down the job offer and move miles away to the old family home, so this is all unnecessary. Similarly, there is quite a bit about the publishers: how they terminate the employment of the editor who is enthusiastic about the books Ben writes and which his wife illustrates, and how the woman who takes over has a much more hard-nosed attitude. Again, this doesn't really drive any of the plot or character development.
The first part of the story, when we are in Ben's viewpoint, works best. As a child, struggling with bereavement, he engages the reader's sympathy. However, the grown-up Ben somehow falls flat as a character, and as he withdraws into his own world, communing with the strange lifeform and/or being taken over by it, it is less and less possible to have any identification with him, so that the sympathetic viewpoint has to switch to Ellen, his wife. Alongside the human characters is the forest which takes on a malevolent personality as it increasingly becomes the abode of something inimical and unearthly, and there is some good description of ice, cold, darkness and general creepiness.
The underlying theme of the book is of a family taint which has come down to Ben and will make him an instrument of the expansion into human space of inhuman forces, yet this isn't really borne out with his children. His son is frightened when the revelations begin to be made at the end of the story, and although there is a hint in the epilogue that he and his sister are perhaps still conduits, it isn't developed earlier. Also, the early part of the story and subsequent revelations about Ben's family make it seem as if only the boys and men are affected, but there is no logical reason for this, or indeed why this force needs them at all. And Ellen's lack of curiosity about what really happened to him at the end is rather odd too. I usually enjoy Campbell's work but found this a little too tenuous, sadly, to rate more than 3 stars.
