Time Curse

What if you had the ability to go back in time and change the worst thing that's ever happened to you? And what if by going back, you might make everything worse? My family has a curse. By using a photograph, we can travel back in time to when the photo was taken. The only problem is, we can't change things for the better. In fact, we tend to make everything worse. Right before my sixteenth birthday, when everything should have been great, my sister died. Aunt Laura says, even though I now have this new ability to go back in time, I can't do it. She wants me to fight it, to save myself from making the mistakes all my relatives have. But I don't care how many times a bunch of people I didn't even know screwed up. That's on them. I won't make their mistakes. I can save my sister. Even if the whole world must pay the price.
