Chaos: Chaos (Paperback)

Aleksandr Zorin is a sadistic psychopath and one of the most prolific killers in United States' history. Exploiting the flaws in an ineffective ViCAP database, he has remained invisible for nearly fifteen years. No one knows he exists. But that's about to change in a horrifying way.

Special Agent Nicholas Keegan is a forensic criminologist working for the FBI's Violent Crimes Squad in Minnesota. An expert in the field of abnormal psychology, he employs his unique expertise to profile and capture society's most dangerous and violent offenders. An unusual case sent his way from a friend in California sets Nick on the path of a killer unlike any he's ever faced.

An innovative overhaul of ViCAP reveals the staggering enormity of the case, and Nick quickly comes to a disturbing realization--his unsub isn't just a killer. He's a profiler.
