Mikis age is never determined but he and his grandfather have differences that can occur between generations. At first the grandfather laughs at the boy who claims the donkey chose its name, but later grows to respect how he treats and cares for the donkey. He no longer looks at it as an animal that he can do whatever he wants to, but one that he needs to not abuse. Working animals that are used to perform human tasks can oftentimes be cruelly treated and the author actually wrote this book while staying on a donkey refuge on the Corfu Greek island. In the author's note he says that the name of the donkey is after the first one retired or rescued after becoming lame from overworked conditions.
There is not much character development and the illustrations are in black and white aiding the reader in visualizing the looks of a Greek village. The steep climbs, tiled roofs, and narrow streets with the Mediterranean Sea as the backdrop add to the flavor of Mikis life. A subplot hints at Mikis' teacher's romance with another man and Mikis romantic feelings for Elena, a girl in his class. I finished this transitional reader in about 30 minutes. While it was sweet, I think it will absorb into the quicksand part of my books-I-can't-remember brain.
