Trailer on the Fly (The Time Travel Trailer Book 2)

How many of us have wished at some time or other we could go back in time and change an action or a decision or just take back something that was said? But it is what it is. There is no rewind, reboot, delete key or any other trick to change the past, right?

Right?
