It's Minky's final year of high school but she still has no idea what she's going to study at university – that is, if she decides to go to uni at all!

With the school bully trying her hardest to break Minky and make her life hell, a time travelling trip to the future comes as an incredible relief. But what happens when she learns not everything in the future is so bright – especially for her family and the city she has grown to love?

Is it possible she could use what she knows to make things better for her loved ones? Could Minky find a way to save millions of people and Sydney from being wiped off the map or is that something that just can't be stopped?

Will she dare to trust her mortal enemy with the secret of her travelling chair?
