You have the power to travel through time.
How you got this power doesn’t matter. It could be the strange pocket watch you found at a mysterious antique shop or a magical diary or even the high-tech phone application your mad scientist father created. However it might be, what matters is that you’ve been using it; travelling back in time to prevent the tragedies that are increasingly involved with your life.
Because this time, someone, somewhere, is behind them. And they keep happening.
