Indigo the Magic Rainbow Pony is the sixth book from the Princess Evie's Ponies series, written by Sarah KilBride and illustrated by Sophie Tilley. Isobel returns to it frequently for its 'bright colours and magical story', but especially for Princess Evie. Or more accurately for Princess Evie's clothes.
Isobel's favourite colour is pink and her favourite activities include dressing up and role-playing. So by the time Princess Evie, in tiara and pink party dress, has been 'whisked away on a magical adventure in a faraway land' where her clothes change to rainbow colours, she's hooked.
The story is as sweet and fluffy as pink candyfloss. Princess Evie, now very much the hippy in multi-coloured stripy tights and sparkly top, follows butterflies to the end of the rainbow. But the end of the rainbow has lost its colour, and it's Evie's job to get it back by collecting seven stones and dropping them in a well.
After a series of adventures in a land that seemed colourful enough, Evie accomplishes her task and the place erupts into an explosion of bright pastels, including a fountain of rainbow bubbles, with 'shimmering butterflies and pretty hummingbirds' swooping 'gleefully through the rainbows'.
'I love it,' Isobel always says at the end. 'Do you think we can go there during the holidays?'
