Liberty Johansen is going to change, the way we look at the night sky. Most people see the old constellations, the things they've been told to see. But Liberty sees new patterns, pictures, and possibilities. She's an exception. Some other exceptions: Her dad, who moved out months ago and hasn't talked to her since. Her mom, who's happier since he left, even though everyone thinks she should be sad a lonely. And her sister, who won't go outside their house. Liberty feels like her whole world is spinning out of orbit. Can she map a new life for herself and her family before they fall too far? -- From dust jacket.
