Society does not make it easy for young people, regardless of their sexual orientation, to find accurate, nonjudgmental information about homosexuality. It makes it even more difficult for young homosexuals to find positive role models in fiction either written or published expressly for them or--if published for adults--relevant to them and their lives. The Heart Has Its Reasons examines these issues and critically evaluates the body of literature published for young adults that offers homosexual themes and characters. Cart and Jenkins chart the evolution of the field of YA literature having GLBTQ (gay/lesbian/bisexual, transgendered, and/or queer/questioning) content. They identify titles that are remarkable either for their excellence or failures, noting the stereotypic, wrongheaded, and outdated books as well as the accurate, thoughtful, and tactful titles. Useful criteria for evaluating books with GLBTQ content are provided. Books and resources of all types are reviewed based on a model that uses the category descriptors of Homosexual Visibility, Gay Assimilation, and Queer Consciousness/Community. An annotated bibliography and a number of author-title lists of books discussed in the text arranged by subject round out this valuable reference for teachers, librarians, parents, and young adults.
