I had a hard time reading this book. It is very dark, like a car accident where I didn't want to look but had to keep looking anyway.
Cassidy is a teenager who has a lot of issues. She doesn't fit in with the rest of the crowd in high school. Her mother left when she was ten and she is being abused by her dad. Her only friends are the ants that she keeps in an ant farm in her room.
Cassidy has trust issues and cuts herself to make herself feel real. As the story proceeds, she has become friends with a quirky girl named Anna and a handsome young man named Jonathan. Both Jonathan and Anna want to help Cassidy, but Cassidy can't accept their help or friendship. Soon she slips into a more disturbing way of dealing with her problems.
This is a good book for readers who want to understand more about psychopaths. I liked the sections in the back of the book which define disorders and vocabulary. If that wasn't there the book wouldn't have the impact that it does. I recommend this book, but not for the squeamish.
