The gang was thought to have operated lucrative drug rings in numerous major cities in the United States, and was implicated in more than 1,000 murders in the U.S. alone. The book traces the origins of the gang, to the internal strife, greed, ruthlessness and infighting that eventually helped to bring it down.

The "Shower Posse" is derived from the "shower" of lead it shoots at rivals. Referred to by the FBI as "the most violent and notorious criminal organization ever in America," the Shower Posse was the epitome of drug dealing ruthlessness.

This tell-all saga is in the words of its mastermind, Vivian Blake. Blake skyrocketed to wealth with savvy business skills, but his savage henchmen terrorized the sheets into submission. Blake's men had been raised in Jamaica where murders went unsolved daily. Shower ran wild spraying bullets on anyone and everyone in their way. Their weapons, fingerprints and m.o.'s were not traceable. Most American police had never seen any of them before. That careless attitude toward pulling triggers earned a record 1400+ murders and quickly established Shower's rep.
