Princess Evie is crazy about her ponies. But Princess Evie's ponies aren't like any other ponies - oh no! Her ponies are magic ponies and, whenever Princess Evie rides them, she is whisked away on a magical adventure in a faraway land . . .
In this sixth book in the series, Princess Evie and Sparkles, the kitten, are whisked away on the back of Indigo the Rainbow Pony to the rainbow's end. There they help to put colour back into a dreary, grey garden - with the help of a few friends, of course!
