Stardust

Three years after Violet discovered the tiny room in her Grandma Dia's house, she is faced with a precarious decision. As an Aliathenian, she feels a particular responsibility to do something about Earth's increasing pace of global warming. She convinces her fellow Aliathenians, Jomo and Chieko, to accompany her on a very risky journey, one they have never attempted before. Ollie's presence complicates matters. Stardust is the concluding book in The Sapphire Eye trilogy.
