Ryleigh Jones always thought her project was good. She never thought that it would change the future.

Fifteen-year-old 'wannabe inventor' Ryleigh Jones knows what she's supposed to do with her life: finish school, then take over the running of the family bakery. It doesn't matter that she has no interest or talents that lie in that direction, or that she'd rather get an apprenticeship and learn a trade. She loves working with her hands and building new machines, but these often cause more harm than good. At school, she is an outcast and frequently clashes with rival Alex Lewis. Both are eager to prove their superiority in robotics and engineering and neither is willing to back down.

When Ryleigh's entry for the science competition, a futuristic refrigerator, malfunctions and sends Alex and Ryleigh back to 2015, they will find that they need to work together if they are going to make it back home. When Alex proposes that they try to stop his parents splitting up, an event that will happen in just a few days, Ryleigh can't say no. After all, there are plenty of things she wishes she could change about her own future.

Along their tumultuous journey, they will find that they have a lot more in common than they realise, and that maybe, just maybe, they can break free from the expectations that condemn them to a life planned out by others.
