While flinch-free books aren’t squeaky-clean Disney-Princess pure in every imaginable way, they are “clean” in the following ways:
They contain no erotica or sexually explicit scenes. There should be nothing that gives a play-by-play description of a sexual encounter or describes nudity in detail. Mild innuendo, reference to sensual or sexual activity that is “off screen” and not graphically portrayed may be used in some books written for adults, but that will show up in the interview with the author on the book’s page.
They contain no graphic violence or gore. There should be nothing that paints a very specific and horrific image in the reader’s mind. Scenes generally described as appropriate for war stories, crime stories, etc. may be present, but that will show up in the interview with the author on the book’s page.
The authors have curtailed offensive language. There should be no use of the “F-word”. Other words commonly considered as swearing and/or racially offensive terms should be used very sparingly, if at all. If such words are present in an effort to mimic speech in times of great duress for a character (and not just peppered in gratuitously), this will be noted in the interview with the author on the book’s page.
