Traditionally a paper-based series, Middle School Confidential adapts its first graphic novel to the iPad leveraging the device’s functionality to infuse a wide variety of sounds, short songs and character voices.

The app takes advantage of zoom features to take readers through panel by panel, providing a sense of forward motion that synchronizes well with the text’s format. Divided into eight chapters, the story introduces relevant teen topics such as body image, self-esteem, popularity and stress through short, everyday interactions among a group of six male and female friends. To round out each chapter, a teen presents a related short message that’s more public-service announcement than component of the story, which may feel over the top to the audience. Each character is presented through actions and dialogue in the short chapters and with a brief bio that includes his or her strengths and insecurities. Additionally, each bio includes an e-mail address, which links to the iPad’s e-mail function; there is no indication of who will actually receive a reader’s e-mail message and what if any response such an e-mail might trigger. The images in the line-and-watercolor panels mirror and reinforce the characters’ related emotions or actions.

A growing-up guide for preteen girls.

This puberty-navigation guide covers girls’ bodily changes, body care, health, relationships with family and friends, staying safe, and handling stress. In many cases the author, a registered nurse, has covered the same material as she did in various editions of this title as well as The Boy’s Body Book. This girls’ book skips the topics of sleep and performance-enhancement drugs in favor of a section on eating disorders. As in the boys’ book, controversial subjects are addressed generally and conservatively if at all. She includes a rough diagram of female reproductive organs and tells her young readers about menstruation and visiting a gynecologist but not how babies are made. She talks about having boys as friends, saying “Don’t put pressure on yourself to call any of your close friendships ‘dating.’ ” The strength of this title is its emphasis on good grooming, healthy living habits, and positive relationships. Added for this fourth edition is new material on interacting with adults, personal empowerment, body language, reputations, and “learning disabilities,” helpful information for the growing segment of the preteen population identified with cognitive and social learning differences. Tallardy’s cartoon illustrations show girls and adults of varying ethnicities and provide a cheerful accompaniment.

This introduction to puberty may be particularly helpful for girls looking ahead to that stage. (resources, index) (Nonfiction. 8-12)
