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. A Teo no le gusta la noche: le da miedo. En cuanto oscurece, se pone a temblar como un dulce de gelatina y se imagina toda clase de criaturas terrorifi cas: una bruja con varita, un dragon verde limon, un esqueleto bailon o un vampiro volador. Pero hay algo de la noche que a Teo si le gusta: su amiga Luna. La quiere tanto que, al verla llorar una noche porque ha perdido su velo de luz, no dudara en emprender un viaje a traves de la oscuridad y en busca de la unica cosa que puede devolverle la alegria.
