Long ago, there was a desert who lived alone in the middle of nowhere. One day, a spring of clean blue water bubbled to the surface of the desert. Together, Desert and Water became the first sisters of the world. Thus begins The Magic Us. Following these mythical beginnings, and after a series of metamorphoses, a new story emerges of Leda and Phoebe, along with their talking cat, Atta. Phoebe is 11 and Leda almost 7. They live in the country with their artist mother and inventor father. According to legend, these sisters and their cat are destined to save the world. To do so, they must journey deep into the Acrimonious Woods, through the territory of the Frustrations and the Mix Ups, into and out of many misadventures, all the way to the castle of evil Catherine, the forgotten sister of Atta. There, in the strange castle, if the adventurers can overcome their fears, they may discover the truth behind Catherine and be able to rescue the lost magic that was stolen from the world.
