Mies Bouhuys (1927-2008)

Dutch author and poet. She trained as a teacher but soon turned to the world of children's TV drama, both writing and directing children's programmes. She also began to write novels and poetry for children, and became highly acclaimed in the field, winning a number of awards. One of her books was a pony story. This was published in English language in both the UK and USA.  As far as I know this is her only foray into equine territory.

Collector's Info:
Fairly rare, the American editions are easier to find than the British edition. Price can vary quite a lot so it is worth shopping around before buying.
