When victims are found in dancing poses, Detective Jo Fournier immediately sees the pattern, but how can a serial killer get to victims all over the country?

When loving wife Jeanine Hammond is found dead in a small leafy town in Massachusetts, newly promoted Detective Jo Fournier is shocked to her core. Why leave her body posed like a ballerina? Why steal her wedding band and nothing else? Hungry for answers, Jo questions Jeanine's husband, but the heart-breaking pain written on his face threatens to tear open Jo's old wounds. It's the same pain she felt when her boyfriend was cruelly shot dead by a gang in their hometown of New Orleans. She couldn't get justice for him, but she's determined to get justice for Jeanine's devastated family.

But before Jo can get answers, another woman is found, wedding ring stolen, body posed in the same ritualistic way.

Digging through old files, Jo makes a terrifying link to a series of cold cases. She knows a serial killer is on the loose, but nobody will listen to the truth—not her bosses, nor the FBI. Still, Jo won't let her superiors keep her from stopping the murderer in his tracks, even if it means the end of her career.

Just as she is beginning to lose hope, she finds messages on the victims' computers that feel like the crucial missing link. But she knows the murderer is moments away from selecting his next victim. Will she be able to take down the most twisted killer of her career before another innocent life is lost?
