In this compelling and utterly addictive thriller, bestselling author Sharon Bolton gives us a fascinating look at the extreme lengths people will go to in desperation, whatever their situation. Perfect for fans of Lisa Jewell, Cara Hunter and Karin Slaughter, it's a dark and decidedly spine-tingling thriller that will get right under the skin...

SHE'S SEEN THE KILLER'S FACE. BUT HE'S ALSO SEEN HERS...

Just before dawn in the hills near the Scottish border, thirteen passengers on a hot-air balloon flight witness a brutal murder. Within the next hour, all but one of them will be dead.

Alone, scared and trusting no-one, she flees for her life, running to the one place she feels safe.

But the killer won't rest until he's eliminated the last witness to his crime . . .
