Hex never meant for the girl to follow him and his best friend Tommo into the woods. He certainly never meant for her to fall off the rope swing and break her arm. When he gets blamed for the accident, Hex runs deep into the woods, ending up in a strange clearing that he has never come across before. There he meets an old woman who offers him a deal. She'll rid the world of those who wronged him and Hex can carry on his life with them all forgotten and as if nothing ever happened. But what Hex doesn't know is someone else has been offered the same deal.
When Tommo wakes up the next day, he is in a completely different world, with only the vaguest memories of the world before. Can Tommo put the world right again? Back to how it was? Or can he even find a way to make a new world that could be better for them all?
