It is Samhain the Blood Harvest. Nonbelievers call it Hallowe'en. The night when eight Nashville teenagers are found dead, with occult symbols carved into their naked bodies. It's a ritual the killers believe was blessed by Death himself.

When children are victimized, emotions always run high, and this case has the public both outraged and terrified: a dangerous combination. Recently reinstated homicide lieutenant Taylor Jackson knows she has to act quickly, but tread carefully.

Exploring the baffling culture of mysticism and witchcraft, Taylor is immersed in a darkness that threatens to unbalance the order of her world, and learns how unchecked wrath can push a killer to his limits.
