The category of Christian interest includes values and inspiration as well as Christian fiction. Books that are written for the Christian market often include scriptural references and rather than the general use of the term God, will refer to Jesus.
Amish romance is a literary subgenre of Christian fiction featuring Amish characters, but written and read mostly by evangelical Christian women.

The genre of Christian Fiction uses all the stylistic rules of the craft but will also include an emphasis on traditional Christian Values. These novels include genres such as fantasy, romance, horror, and history. Christian novels avoid offensive language and taboo topics and focus on faith in God, Scripture, and Jesus. Another common thread is something important to the Christian community and typically a happy ending.

A separate and surprisingly cross-over genre are books about the Mennonite and Amish communities. They are typically uplifting and invite readers into a world typically only those communities will ever see. They also include many popular romance authors. The appeal for many readers, both Christian and Secular, is the lack of graphic descriptions of sex so often unavoidable in popular media.
