What would you do if you could go back and change anything in your life?

Adam and Jules have been married for twenty-five years when they discover a time machine in their garden shed. Miraculously powered by the old mixtapes they’ve given each other over the years, it allows them to travel back to pivotal moments in their relationship.

They can now relive the moments that made them fall in love. Fix the mistakes. Choose differently. Perfect everything.

But soon they discover that playing ‘what if’ is as dangerous as it is addictive. As the ripple effects spiral out of control, can they find a way back to their messy, glorious real life? Or will they lose each other forever?

If it was you, what would you dare to change?
