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 gave her the stars. 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 and lonely.

And her sister, who won't leave their house.

Liberty feels like her whole world is falling from space. Can she map a new life for herself and her family before they spin too far out of reach?
