When Emma is approached by DCI Greyson to assist with a case, her first instinct is to say no. Still shaken by the attack on her life six months earlier, and balancing her friendships with a budding relationship, she'd prefer to stay clear of the danger. However, circumstances force her hand and she throws herself into the investigation. She soon realises that her target isn't a mysterious creature, but a dangerous man without the slightest care for human life... Can Emma survive the biggest risk she's ever faced, or will she have to sacrifice too much?
