Fourteen-year-old orphan Remmi Clearwater has a secret that could get her killed. For years, she has lived in the cavern lands of Penumbra, the dreariest land in a parallel world called Dreamearth, which people from Realearth visit while they sleep. All her life, she had successfully hidden her multiple magical abilities out of fear that someone would discover the truth about her. These amazing talents strongly hint that she's a Halfling, the child of a Dreamearth mother and a Realearth father. Such mixed heritage isn't only taboo, it's a death sentence. Halflings in the past have caused disasters in both worlds. When Remmi's magic is exposed, she is forced to flee Penumbra, only to find that her newfound freedom comes with its own set of risks.
