On their wedding day, Jack and Rachel were deeply in love. Ten years later, they were divorced. Now they've been living apart for six years; Jack rarely sees their two teenage daughters.
The call comes in the middle of the night. Rachel is comatose after a car crash, and Jack's children need him. The timing couldn't be worse, but in minutes Jack's on the road south to be with his family.
Rachel's coma lasts for sixteen days. During that time, Jack comes to know her better than he ever did - through the girls, through Rachel's friends, through her art. And he begins to realise what he lost when he let Rachel go.
As they re-discover each other, Rachel and Jack show us that sometimes being knocked violently off course is the only way we can gain our bearings and find our way home - back to the people and places that matter most.
