The Boy with 17 Senses

Every resident of the planet Yipsmix has synaesthesia - they don't just hear sounds; they see and taste them, too. On this unusual planet, poor Jaq Rollop must save his family's farm. To do so, Jaq is forced to sell his beloved pet and only friend. Trusting and naive, Jaq gets swindled into trading his pet for a seemingly worthless key. But then something very strange happens. The key leads Jaq through a wormhole to a terrifying and magical land full of riches, overwhelming sensations, and giants. The name of this frightening land? Earth.
