On the run with a newborn son, serial killer Samuel H. Knight - now using the name Matt Cooper - has mellowed out. He just doesn't have time for murder when he's busy changing diapers and filling bottles. All that changes, though, when a bounty hunter named Allison Underwood knocks on his door. Not only is she F.B.I. Agent Kathleen Underwood's little sister, but she wants Knight's help in murdering a dangerous cult leader named Aaron Castor. The catch? Castor is claiming to be the serial killer Samuel H. Knight, and his cult is filled with hundreds of women who call themselves Jessie Coopers - and who willingly wait in line for Castor to murder them so that they can ride his coattails to heaven. Book #3 of the startling serial killer diary series brings out a more thoughtful and calm version of its dangerous antihero -- calm, yet always on the brink, both fearing and anticipating what might push him back to his old ways once more.
