I recently re-read NATIONAL VELVET for the first time since I was a teen, 40 years ago. I was struck by the vivid, realistic and detailed descriptions of a wide variety of horse personalities, told from the practical viewpoint of a truly rural-raised author. I was also struck by the rich tapestry of village life, family life, and so many fascinating personalities, especially Velvet's mother, who knew from hard experience the pitfalls that fame can bring. The book's end is an enchanting, uplifting surprise -- not the outcome of the famous race, but what follows after. In short, the book I enjoyed at age 15 knocked my socks off at age 55. It is not an "easy" read, and I realize now that most of it went over my head when I was 15. There are no footnotes to help interpret local dialect and customs from rural Britain in the early 1900. But nevermind the occasional word, phrase or deed that seems unfathomable to modern readers -- just enjoy the ride!
I'll have to add the first two to my reading list! I've read the other two - both are excellent books.
