Containing more serious subject matter than the cover would lead you to believe, Nugrl90(Sadie) is a worthwhile read for teens (rather than the publisher's recommended age of twelve). Divorce, relocation, making new friends, and a serious romantic relationship are at the core of this story. Depression, domestic violence, reckless behavior, and anger issues are also of importance. The main character is involved in a relationship with a boy who encourages destructive behavior and who abuses her physically. She displays great courage by speaking to the administration at her school after learning that her boyfriend has brought a loaded handgun to school. Underage drinking, smoking, partying, and making out occur. A rather in-depth discussion takes place between mother and daughter with regard to sex and birth control. Language is somewhat strong (d-ckhead, a-shole, "f***"). The main character cuts class and sneaks out at night repeatedly, spending time with her boyfriend. Religion plays a role in this story, and one blog entry reads, “itz not ok 2 b gay, itz a sin.” The main character goes to therapy and begins taking antidepressants, which help her immensely. Family, though troubled at times, is supportive when support is needed. Overall, this story conveys positive messages about self-respect, the value of friendship, and reaching out for help when it is needed.
