If you had the power to change the past. . . where would you start?

Cassie has never really fitted in. She remembers everything. Understands nothing. And consistently says the wrong thing.

So when she gets dumped, fired AND her local café runs out of banana muffins - all in one day - it feels like the end of the world.

But then Cassie discovers she has the power to go back and change things.

With endless chances to get it right, can she stop it all from going wrong?
