Despite what the talking heads say, all writing advice, even if it is from so-called writing experts, is not always the best advice for your type of story. Analyze your own story and see which flow best suit it. You can create your own signature flow.
I recently read where a writing tip advisor said: One should list all the main characters on the first few pages of the novel.
[This good advice if you write children books or young adults books, but it can not be done with all young adult books.]
That is only possible if the story is short with only two to four protagonists. But it is impossible if the story is long and the main character’s life venture into other locations and they meet other people. Especially in long novels. It would seem silly to add someone from the character’s adult life whom they haven’t met yet, if the story is a life progressive story.
A life progressive story or novel aren’t common nowadays because they are hard to write. But they usually start with a character in their youth and narrates as they live their life. Therefore, you introduce new characters, and even bring back old characters from afar throughout the story. In life progressive stories everyone doesn’t die off because the writer knows how not to write themselves in a corner. They don’t leave corpses in every room in the house.
This advice is not recommended if the antagonist is someone the author specially designed to keep the protagonist on their toes. Don’t give away too much too soon. That spoils the story.
Some might say every antagonist fits this bill, but no they do not. Well, always in a clear, precise manner.
For example: In the first book of the Unholy Pursuit series, I do not tell who is Ana Bufaye’s archenemy in the beginning of the story. Readers don’t learn who he is until later. In the beginning, I wanted to introduce the main character, her backstory, and her plight. The other main protagonist, Bea Wyett, her daughter, and her two love interests are mentioned in the beginning, but not her adversary and his main men. I tell what her opponent is doing, not his name.
