Sam is seven years old and living in Beverley, Massachusetts. She adores her father, though he isn’t around much, and her mother struggles to make ends meet. Sam doesn’t fit in at school, where the other girls have the right shade of blue jeans and don’t question the rules. All she wants is to climb. Hanging from the highest limbs of the tallest trees, scaling the side of a building, Sam feels free. As a teenager, Sam begins to doubt herself. She yearns to be noticed, even as she wants to disappear. When her climbing coach takes an interest in her, his attention is more complicated than she anticipated. She resents her father’s erratic behavior, but she grieves after he’s gone. And she resists her mother’s attempts to plan for her future, even as that future draws closer.
