I lied in my last comment on Angela's Ashes. I forgot that I also read The Art of Racing in the Rain. And, I forgot to mention that I really really liked it. Oh. I lied again, I actually listened to it on my iPod and so did Mary Rollins. Audiobook or not, this was a book I would have liked in either format -- read-to-me or read-it-to-myself.
I think you all would like this book for the primary reason that it's a story told by a dog and I know how we all feel about dogs! The narrator-dog, Enzo, is a deeper and more philosophical dog than your average Gus/Howie/Cleo. He's spent a good bit of time watching television and thinking about things in addition to his next meal, the beach and walks, he practices unconditional love and believes that he has some terrier in him. His insights into both dog and human nature are brilliant and the telling of his family story is bittersweet and lovely. I won't ruin that for you by summarizing in case you decide to read it. However, I'm looking at Howie and Cleo at this very minute asleep on the blue couch in the computer room and wondering how they would tell the story of the Mathews' family.
