The main character, usually a woman, finds out about a book or book series of fiction having some grain of truth. The main character usually has some relation to one or more of the characters from the original works, which she most likely already read. Plus, at first, the main character doesn’t believe that some variations of the book or book events are accurate but eventually becomes convinced of the reality.
There’s generally at least some fighting, plus how dark it varies from book to book. The same can be said for traveling. Unless it was stated in the story that she was trained before the story’s beginning, the main character must do some training within said story.
