I have mixed feelings about this book. I think the part that was most difficult for me with the point of view in which this books was told through. The dog just wasn't all that believable as the story teller. There were so many times throughout the book that the dog just had way too much to say about people who he just really didn't know all that well or had thoughts that were so deep on the moment that I had a hard time thinking that this point of view worked. I think putting it through the dog's point of view really distanced me from the other characters as well. I didn't feel like I could love a whole lot about anything in particular about these people except for Denny and that was because he was the dog's master. This was one of those books like a mediocre movie that things start happening slowly and by the time you get half way through, you aren't emotionally invested in anything, but you just want to find out what happens because it's one of those stories that are so "out there" that you feel like the ending is going to be pretty well wrapped up. Because otherwise if it's not, this book/movie would have had no purpose in being written. 
 Ending on that note, the book was quite well strung together and had the dog been anyone other than a dog, I would have thought the person had very eloquent thoughts. I also tended to skip when Enzo the dog started getting really into having a monologue about the people who raced and where they raced at, and would skip to the racecar fortune cookie parts and the analogies of racecar driving with life and it's ups and downs. 
 Eventually towards the middle (like page 190 of 321)I just wanted to find out the obviously happy result of an extremely depressing book; because lets be real here, this book would have no ultimate point of there wasn't some sort of happy ending. Thankfully I was given my bittersweet ending and what was foreshadowed in the beginning few pages, happened in the very last pages. Thank you, Enzo the dog, for showing the world what the life of dogs may actually be like (coming from a dog lover and owner). 
 I would only recommend this book if you are okay with the idea of a dog being the story teller and if you like or have a vast knowledge of the racing car world.
