What is the author's style in All Things Bright and Beautiful by James Herriot?

This novel is a fictionalized autobiography of Herriot's early years as a veterinarian and thus is written in the first person by Herriot. He tells his experience from his point of view. Herriot does not speculate about circumstances but tells only things that he has witnessed personally. This first person point of view fits Herriot's intentions for his novel perfectly. It is though this outlook that he is best able to share his experiences as a vet as well as the valuable lessons he learns during his early years of work.
