Blood Oath — Michael Lister

A missing young man. A sadistic serial killer. John Jordan is once again carrying a gun and a badge - and he's going to need them.

Balancing family life with being a cop and a prison chaplain takes grit and grace - and John has plenty of both. Working two cases that may or may not be connected, John is investigating the disappearance of a young army ranger home on leave and one of the most sadistic serial killers he's ever encountered.
