As someone who is involved with racing, I can tell that Garth has done his homework here. As a general animal-lover, I couldn't imagine how the title could relate to a dog. This is easy to read - short chapters that consolidate various thoughts and actions. In fact, I couldn't put it down. I read the entire thing in 2 sittings, starting on the flight home from a race, irritated that I had to turn my Kindle off during landing.
The story involves a guy who is an amateur racer - SCCA and that type - but still has a day job. He dreams of hitting the big time, and shares his thoughts and dreams with Enzo, his dog. The two share life's trials and tribulations, through Denny's marriage and what comes afterwards. All through Enzo's eyes.
The story takes some harsh and unhappy turns. I found myself thinking that it was a sad story, but after I finished, it somehow stayed with me. I kept thinking about it, and it grew on me. I ended up thinking what a great story it turned out to be. It does take a surprise turn at the last minute. I should have seen it coming, but didn't.
I would recommend this story, even if you're not a racer, or a dog. Easy to ready, good moral story, and more thought-provoking than you think it will be.
