The story takes place primarily in the back garden — a sprawling, magical New Zealand bush and forest that, unknown to most, sits on a Thin Place: a natural crossing point between ordinary reality and Luminos, the Shimmering Realm, a world of pure magic where unicorns, dragons, and fairy-folk live alongside each other. The crossing point is hidden inside a massive, ancient pōhutukawa tree.A young unicorn named Prism has fallen through a crack between realities — pulled off course by the mischief of The Smudge, a villain who is less terrifying monster and more bumbling, grumpy, cloud-grey fox.
