This is a boy's make believe, being a fire fighter. He's fairly detailed, describing how he puts out the fire, saves the family, and rescues the pet. I do find the use of "pet" instead of the more specific "pet snake" to be odd.
I do find the book to be a little banal, there are better firefighter books out there. However, if your kid is really into firetrucks or it's on sale, this will help round out your library.
