Santeria markings. Hindu magick. Druidic runes. Japanese mysticism. The latest series of murders in Somerset has everyone confused, including the local police and the Medical Examiner's office. They seem to be the work of one killer, but each murder has a completely different, ritualized, M.O.

Working alongside her boss, Dr. Slikowski, Jenna Blake is back on the research trail, trying to discover the identity of the killer. Unfortunately, Jenna is still grieving over the murder of her friend Melody, and is becoming distracted by her growing feelings for Somerset detective Danny Mariano.

Jenna needs to do some serious soul-searching. Her mind isn't on the job. But if she doesn't start paying attention on and find the connection between these ritual murders, Jenna may not survive her first semester.
