Celina throws the egg right at the old, crazy cat lady Silly Sally by accident because her eyes were closed, but the other kids don't know that and think Celina is the greatest for doing it. After the kids run away so they don't get caught, Silly Sally makes Celina promise to get her new Siamese cat, Constantine, off her refrigerator or else Celina's father would find out about her egg prank. That's the worst thing that could happen. Celina never wanted to let her dad down again.
On Celina's first try with Constantine, he scratches her up and the sight of the blood reminds her of her mother's murder she witnessed a year before and has all but blocked out. As the summer unravels and Celina's lies to people pile up in effort to hide from her father her terrible act, she must find the right decisions and make bold confrontations, both to other people and herself, to figure out how to make everything right again.
