I think this book is very much a book to read for reading sake.  It’s a long winding narrative that explores the life, thoughts, feelings and motives of the main character.  This is a literary mystery with a pretty obvious ending with an unreliable and oddball narrator.  The mystery is a delivery device for the development and character exploration.  But there is also plot development in a lyrical, thoughtful and atmospheric way.  With very strong descriptions of nature and animals.  The William Blake references and the authors own writing style adds an interesting Grimm fairytail tone to the book.
