Ginger is initially distrustful of the stranger in the park who is watching her and her friends, but then she notices how much he looks like her biological father who left so many years ago. Now that she knows who she is, she opens her life to him and helps him figure out a way to confront her mother about her Dad's reappearance into her life. But everything is not quite what it seems.
A functional, but largely by-the-numbers story about family, trust, and a couple other things that I can't reveal because it would ruin the ending, this is a Delacorte prize winning story. I'm not quite sure it lives up to the hype, mostly because the ending is a bit too predictable, but it is a good read.
