Another fun and educational young reader's horse book is The Diary of a Horse Mad Girl by Katrina Kahler.
Written like a diary by a soon to be nine-year-old girl in Australia, Abbie, this story explains the joys and a few disasters of horse ownership. Her new pony is named Sparkle and is a palomino. I wonder why there is a bay on the cover? But there are photos included, some of Sparkle as well as other horses and animals on the farm.
