Touch of Shadow - The Shadow Sorceress, #5

The dead aren't staying buried in King City. Amber is called to investigate the discovery of a newly-murdered young woman, whose death was part of an occult ritual. This case is anything but routine: the woman was only murdered 24 hours ago but her ghost has been haunting Amber for the past three months. Now the ghost has vanished and is unavailable for questioning, leaving Amber with a body but no leads.
That isn't the only danger the city faces. The dead have begun to rise, heralding the arrival of something even worse. A young boy bears the same demon mark as Amber, leaving him vulnerable to demonic possession. His soul hangs in the balance between life and a fate worse than death. Something wicked this way comes. And it's ready to raise hell.
