A book isn’t an issue book because it contains a minority character. – s.e. smith
Most, if not all, mainstream genres have a dearth of minority characters, whether they be supporting cast or the protagonist. One of the explanations given is that books with minority lead characters are seen as issue books, i.e. the character has to be struggling with some issue of their identity and the whole story has to be about that issue. While issue books are important for the value they bring to a topic, having a minority character does not equal an identity struggle to be overcome. Minority characters can be included in any type of book, from science fiction, to horror, to mystery, and all the genres in between, without their race being the focal point of the story, or a hindrance to their character’s capabilities.
