Retired serial-profiler Frank Black has moved his family to Seattle to escape the violence and horror he dealt with while working for the FBI in Washington, D.C. Although his uncanny and often unsettling ability to see into the twisted minds of serial killers has caused him much inner torment, Black knows his gift can still be used to help protect and save others. For that reason he has joined the mysterious Millennium Group, a team of underground ex-law enforcement experts dedicated to fighting against the ever-growing forces of evil and darkness in the world.
