Something sinister is at work in the Louisiana bayou: a methodical killer with a penchant for medical experimentation is hard at work completing his most heinous crime yet, taunting authorities who are desperately trying to catch up.

Dr. Wren Muller, a forensic pathologist, is the best there is. She’s never encountered a case she couldn’t solve, thanks to her encyclopedic knowledge of historical crimes and years of experience working in the Medical Examiner’s office. Until now, that is. Case after case piles up on Wren’s examination table, and she soon finds herself sucked into an all-consuming cat-and-mouse chase with a brutal murderer who grows more brazen by the day.

The Butcher and the Wren promises to ensnare all who enter with details straight from the morgue that only an autopsy technician could provide.
