My family and I are working our way through this excellent series of audio books. I read them way back when, as the author was writing them, and while I completely enjoyed them, I missed a lot because I had no idea what the Yorkshire farmers were saying. In this version, the reader delivers the vernacular in such a way that I have no trouble understanding, whatsoever.
Christopher Timothy, the reader, is the actor who played the role of James Herriot in the television adaptation. He really does an excellent job of reading these stories.
While there is a thread which runs through the books, each individual chapter really does stand alone, as its own little short story. This is a good choice for those times when you would like to follow an audio, but can't quite listen to it as often as you'd like. You don't really have to remember the "back story," but can just enjoy each new story as it comes along.
These books really aren't about animals at all. They are about people, their eccentricities and their delights. I highly recommend this series of books in print and in the audio version. My print collection is on my feel-good bookshelf. These books belong on every shelf. They really are that good.
