What if?

What if your life and the world around you would change, because you made one little mistake. What if you gain to much power and life decides to take it all away from you, for your own good. What if your sister would use her power to go to a live The Beatles concert, and has a one night stand with a random guy, and because of this the world you knew is no longer there. This is exactly what happens to fourteen year old Chloe Jackson.
How can Chloe and her seventeen year old sister, Rebecca, take back what they've ruined, their life.
