One popular book person in fiction is Sherlock Holmes. He is a brilliant detective created by Arthur Conan Doyle. His deductive reasoning skills are legendary and he has been adapted into numerous movies, TV shows, and other forms of media.
Some common names in historical fiction books could be Elizabeth, William, Henry, Catherine. For example, in a historical fiction set in medieval England, these names would be quite fitting as they were popular during that time period.
Some people might misunderstand it due to lack of knowledge. They may misinterpret some of the more extraordinary stories in it as science - fiction - like elements, but in fact these are part of religious narrative.
There could be various relationships. If the fiction is about a small town's magical elements, the 'book angels' might be protectors of the people from town, and mom could be one of the people they protect. Or mom could be the one who introduced the concept of 'book angels' to the town, if she has a special knowledge or connection to these angels in the context of the story.
Yes, it's possible. Book collectors or enthusiasts might have memories associated with buying murder fiction. Maybe they remember the excitement of finding a rare murder mystery at a second - hand store or the anticipation when ordering a new one online.
Maybe it's a science fiction book with some kind of technological glitch or time-space anomaly that makes people and objects disappear. Or it could be a horror story where a supernatural force is at play.
