Just came upon another really interesting idea for your story's hook.
Hook your audience by introducing an element of mystery into the opening of your story.
I read about this in author Mark O'Bannon's free e-book, entitled How to Tell a Story, which you can find on his website, www.BetterStorytelling.net.
This book is very simple, only 31 pages. But I actually use it a lot to help me plot out my stories.
Perhaps because it is so simple, it helps one cut to the chase and plot out a simple method to tell your story, instead of a convoluted one.
O'Bannon bases his storytelling techniques on his years of study of story structure as well as on John Truby's methods.
