Anyhow, Jump is the latest Jilly Cooper and was just recently released and because I am busy, I haven't actually finished it yet but 1/3 of the way - they're very thick and heavy - and I love it!
You know you're on to something good when it takes 15 minutes to read through the character- and animal list.
I don't think you have to be into horses to appreciate her books but it helps, and all you really have to get over is the horrendous 80's hairstyle Jilly Cooper is sporting on the sleeve. But it's a minor thing. You can always remove the dustcover when reading it.
I'll do an update when I've finished it.
