Twelve-year-old Neva and her older brother Clayton have been left with their grandparents for the summer, and she is having a difficult time dealing with change: the changes to her body, changes with her relationships with her brother who is becoming involved with social activism and their multicultural community (and with Michelle, the sexy girl across the street), and with her best friend, Jamila, whose father is from Ghana--Neva is growing up and she is not sure that the dictionary has the right words to describe everything she is experiencing.
