A Life for a Life (Detective Kate Young)

Nobody can get into the mind of an erratic killer―except an unpredictable detective.
When a young man is found lying on a station platform with a hole in his head, DI Kate Young is called in to investigate the grisly murder. But the killing is no one-off. As bodies start to pile up, she is faced with what might be an impossible task―to hunt down a ruthless killer on a seemingly random rampage.
Meanwhile, Kate has her own demons to battle as she struggles to come to terms with her husband’s death. And she is hell-bent on exposing corruption within the force and bringing Superintendent John Dickson to justice. But with the trail of deception running deeper―and closer to home―than she could ever have imagined, she no longer knows who she can trust.
With her grip on reality slipping, Kate realises that maybe she and the killer are not so different after all. But time is running out and Kate is low on options. Can she catch the killer before she loses everything?
