Libby Anderson, who now runs Teamwork Dressage in America with her daughter, was born and brought up in Australia. She started her equine career jumping and eventing, and then went to a show jumping clinic run by Franz Mairinger, then the Australian coach for show jumping, cross country and dressage and formerly chief first rider with the Spanish Riding School in Vienna. It was a pivotal moment: she saw the possibilities of dressage, although she continued to jump until a fall when she was three months pregnant.
She competed internationally at dressage, and judged to International FEI level until 2004. She continues to train and teach at Teamwork Dressage. She has written many scientific articles on equine nutrition, as well as writing on horse care. Her two pony books are aimed at entirely different age groups: A New Horse for Marny is aimed at teenagers, and The Gundaroo Pony at younger readers. A New Horse for Marny is well worth seeking out in its American printing. It has a beautiful cover illustration, and that rarest of the rare things in the modern day horse book, has internal illustrations as well.
Finding the books
The Gundaroo Pony is reasonably easy to find. A New Horse for Marny is much trickier to find, but not impossible.

Teamwork Dressage: run by Libby Anderson and her daughter. A slightly confusing site: it switches from third person to first with alarming frequency.
