Just purchase Construct 2 and let see how to make a story book.
I would think it would be very easy to make that. As long as you have a good story and the art resources, the actual coding in Construct 2 would be hardly anything.
If you want to have the reader actually interactive with the story and do more than just pick the next page or something on the page, then the game could grow in complexity.
But, I think this is a good idea and would like to see your finished idea.
