The Corgi Chronicles - Laura Madsen - Bog

Pippin may look like a big-eared, short-legged dog, but he's a magical corgi. Fairies ride corgis because they're too small to ride horses. Pippin lives undercover with a human family but his secret mission is to serve Aliiana, an earth fairy, as her faithful steed. Aliiana and Pippin learn that a thief has stolen the Ruseol Gem, the source of all good magic on Earth. If the thief destroys the Gem, all magic will wither and die-including Aliiana. Can they stop the thief before he kills magic?
