There are five novels in the "Twilight" series, the original novel of the movie "Twilight". The first is called "Twilight", the second is "New Moon", the third is "Eclipse" and the fourth is "Breaking Dawn". In fact, the novel has ended as of the fourth part, and the "Midnight Sun" I am translating now is the fifth step of the novel. This book uses the male protagonist Edward as the first protagonist, and uses first-person statements to describe Edward's inner activities in the story that happened in the first book. There are many things that were not shown in the first book or the movie Twilight. After reading it, I felt that many details would be much more vivid if the inner activities of the characters were added.
