Thank you so much for your question. I love hearing from other writers! First of all, congrats on already being hard at work on your books. That’s awesome! I can’t wait to read them one day and hope that I can be helpful to you in the meantime!
So your question was about writing an exciting prologue and introduction. The truth is, I don’t actually write prologues or introductions for my books! I think that it can be a better experience for a reader to dive right into the story, and learn the important information they need as they go.
You mentioned using the show-don’t-tell method to give info to your reader—I would look back through your outlines for your prologue and introduction, and highlight the information you think the reader absolutely must know about the world your book is set in, or the characters they’ll be reading about. THEN see if there are ways in the first few chapters of the book, to slip that information right into the story, using the show-don’t-tell method.
Here’s an example from my book:
In Secrets of Bearhaven, Spencer’s parents founded a safe haven for rescued bears. They did this before Spencer was born, and have been secretly rescuing new bears to bring to Bearhaven for Spencer’s entire life. The reader definitely needs to know a little bit about Bearhaven’s history in order to understand and believe the adventure that Spencer goes on throughout the course of the book.
If I were to write a prologue or an introduction to Secrets of Bearhaven, telling the reader about Bearhaven would be important information to include. Instead, in the first few chapters of the book, Spencer discovers Bearhaven himself, and through the questions he asks other characters, and the observations he makes in Bearhaven, he learns the history, and the reader learns that information along with him.
One of the best parts about reading is learning with characters, discovering new things about them as you follow them through their adventures, and watching them change as people (or bears!). You don’t want to do too much work in a prologue or introduction that might take away from the discoveries that the reader can make throughout the course of your book.
I know this is SUCH A LONG ANSWER!!!!! But I just want to say one more thing!!!
As authors, it’s important for us to know our characters really really really well. The same goes for the world we’re writing about for the character to live in. But you don’t want to overwhelm your reader with too much history or background information before they get to the real heart of your story.
I hope some of this helps! At the end of the day, do what you think is right for the story you want to tell. And keep writing :)
From one author to another, wishing you all the best,
