Time Travel

What is the main reason authors should use flash backs and flash forwards? Can you think of some examples of this technique in books you have read? How about in your own writing? Before you comment on this post, take some time to find a great example to share in your comment. Please do not share an example that I have already shared in class. Look at your own writing, look in your library books, or look in books around the room. As you consider your example, think to yourself does this flash back or flash forward really help to create a strong emotional connection?
