This book was fantastic. There were so many twists and turns, I was suspicious of everyone.
In addition to being a great mystery/thriller, the novel also provides commentary on systemic racism, both in schools and in general. For example, Devon lives in a neighborhood where people are kept poor and can't find good jobs. Devon himself has resorted to drug dealing to support his family. The book points out that black people are sent to jail for trying to survive in the only ways they can.
Chaimaka lives in a rich, mainly white neighborhood. Her family is wealthy, and she expects to go to college and get a good job. However, she is expected to "act white" by straightening her hair, using a nickname, speaking "properly", etc.
The relationship between Belle and Chaimaka had me screaming. They clearly care about each other, which makes it even more frustrating when her secret is reviled!
