Teo doesn t like the night; it frightens him. When it gets dark, he begins to shake, and he imagines all kinds of terrifying creatures: a witch with a magic wand, a lime-green dragon, a dancing skeleton, and a flying vampire. But there is something at night that Teo does like: his friend Luna, the moon. He loves her so much that, upon seeing her cry one night because she lost her veil of light, he doesn t hesitate to embark on a journey through darkness in search of the only thing that will make her happy again."
