Simmons, R. (2002). Odd girl speaks out: Girls write about bullies, cliques, popularity, and jealousy. San Diego, CA: Harcourt.
This is a fascinating collection of writings by girls themselves, collected and edited by Simmons after inviting them, after reading Odd Girl Out, to write about their own experiences. Much of this bears out the findings Simmons published in her original book—only in the voices of girls ages 11-16.
