We meet Enzo the dog on the eve of his death, where he tells his touching, funny, and sometimes saddening life story. From puppy-hood to adult-hood and his old-age. He is chosen by his master, Denny, and remains loyal to him all of his (Enzo's) life. Not only do we see Enzo's life, we see Denny's and his family's life as well. Through all of their goodness and struggling through tragedy, Enzo shares all in a particularly touching way.
That is all I shall say; as I do not want to end up giving too much away. It is a touching read and I would definitely read this again sometime. Highly recommended.
