Thank you R-Tech and Yaghish.
At first, I didn't think the Frame Story format was even remotely close to what I was going after, but on further thought I think it is. From what I can see, the Frame Story is nothing more than using flashbacks, but where the flashbacks are the main component of the story. Am I on the right track here?
Yaghish hit it on the head when describing that both stories get solved in the present with the past story becoming intertwined with the present story.
I guess what I need to research further is how to jump back and forth. My fiance told me that using dates at the beginning of my chapters might be the way to keep the reader informed of what time I am taking them to. I could also start the chapter in the present and flash back, but I would have to start half my chapters this way and it might get painfully repetitive.
I went to the bookstore this weekend to find some novels like this, but came up short. How do you search for books on a style or format, rather than genre?
