The book will always be compared to the movie, and in many ways, I agree with those on here who have admitted liking the film better. Both are sad, but for very different reasons. The personal history of the main character has been completely changed, and with that, what drives his push for survival...if that's what it is. There is a scene at the beginning of both that has Ottway kneeling with a rifle in his mouth, and the burden that pushes him to this place in the film feels somehow simpler; more sorrowful. It is completely different from why he does it in the book. Both the film and the book Ottways are dark, damned, lost souls, but the one in the book is darker, less confident, and less redeemable. I wouldn't dream of spoiling either, as the poetry of how these things gets revealed is part of the joy of the experience. While I enjoy the film immensely, (it was one of my very favourites from this past year, and possibly of any year), I will say this: the wolves in the book act more realistically than the ones in the film. But the film wolves, to me, feel more elemental; they are a force of nature, mirroring the storm that is pursuing him from within. Some of that comes out in the book as well, just not as much. And in the film, Liam Neeson comes across as something of a force of nature himself, whereas the written Ottway is just a man with a troubling past. I do recommend it, though. Especially if you really loved the movie and are interested in a sort of alternate universe version of the story. What you won't find, much to my disappointment, is the poem Ottway recites several times in the film, written by his father. I think about that poem a lot, and was disappointed that it didn't appear in the source material.
