Ian Grayson's priority is to protect the artifact which could be the answer to all his questions, but he has already been chased across Belize and Mexico by those who would take it from him by any means necessary and he is desperate to find a way to escape from them and get home to Chicago. When he persuades a trucker to give him a ride he has no idea that his life was about to take a whole new direction. When Mackenzie Wallace picks up an unlikely hitch-hiker he soon discovers one should never go by first appearances, Ian Grayson was certainly not what he expected from a Doctor of Archaeology.

Ian’s experiences with Christmas have never been particularly good and Mac wants their first Christmas together to be something special, a time Ian will always treasure. As ever, things don't quite go according to plan.
