Each book in the Manege de Zonnehoeve series tells the story of a different pony. Bella is cute and very small. She lives in a meadow next to the Zonnehoeve. As soon as she gets the chance, she crawls between the wires of the fence, because she finds it much more pleasant at the Zonnehoeve than at home. There is always something to do there and there are children! Bella can't imagine anything more fun. Unfortunately, Bella's owner has very different plans for her. She must become a show pony and win inspections! But that's the last thing Bella wants...
