Australian soccer mum Sarah Calhoun keeps the terrifying secrets of her time as an overseas aid worker from everyone she loves. Until two men from Northern Ireland hunt her down - one an obsessive policeman with demons of his own, the other a brutal IRA executioner, too closely connected to her past.

She is forced to return to Belfast to testify at a murder trial. But she faces an impossible choice - lie on the stand and allow a vindictive killer to run free, or tell the truth and place her children in the line of fire.

With the lives of her family and thousands of innocent people at risk, Sarah must battle her fears, overcome betrayal and find the courage to fight for the truth.

But righting the wrongs of the past just might cost her everything.
