12 Books Banned in US Prisons

"From tarot card guides to coloring books to a Frozen novel based on the Disney franchise, the books banned in US prisons are often seemingly harmless. State prisons provide explanations that describe the books as "sexually explicit" or "a threat to the order and security of the institution," but their reasoning is vague and doesn't explain why the content is considered a threat. In fact, in many states, Dungeons & Dragons guides are prohibited for fear of inciting violence and "gang activity" with little to no explanation."
