But as his past catches up with him, he discovers that there's a price to pay for his murderous desires. Death waits at his doorstep and it causes him to act in ways no one could have ever anticipated.

Korzh's efforts are still going strong as haunted antiques continue to grip the world in their claws of terror. The latest is an eerily cold, silver class ring that drives its wearer into a frenzy for human flesh. A brutal urge to plunge a knife deep into innocent bystanders is overtaking the residents of Concord, New Hampshire, and no one is safe.

An unlikely alliance is formed between Ariana Leckie and Victor Daniels on their hunt for Stefan and the collectibles. They're determined to bring an end to the misery he has caused, no matter the cost. But first, they have to address the threat growing in front of them.

Meanwhile, Tom Crane is enjoying his life with a loving father figure, a caring girlfriend, and a growing list of friends by his side. But his life is thrown into chaos when an old acquaintance drags him into their quest for revenge. Trapped and alone, Tom must find a way to escape before he's too far gone.

As their lives collide, they'll soon discover that vengeance exacts a heavy toll on both the living and the dead...
