Is Sara mad or haunted? Mad or haunted? The question keeps recurring and won't be laid to rest. There are real unexplained phenomena that others experience but this is the ordinary world of London's chattering classes and solid rural folk. Why does the ground resist Tom's powerful machines? Is he just an inept yuppie pursuing a false rural idyll or is there a supernatural force against him? Sara subconsciously yearns for a child but her conscious self is in a comfortable pact with Tom, enjoy life, no children. The reader senses the tension in her psyche creates a distorting prism before Sara's eyes, but this is the reader's only view of a world, at once strange and commonplace. After many twists and false leads we reach a final conclusion, which somehow seemed inevitable in retrospect. This is a book I feel Stephen King would have been proud to have written, if he ever read it, and if he hadn't written quite a lot of good books already, well you know what I mean.
