Charles Manson and the Manson Family
The Crime Library particularly recommends two books on Manson. Helter Skelter by Vincent Bugliosi is a very thorough examination of the Manson case and trial by the prosecutor. John Gilmore's The Garbage People: A Trip to Helter Skelter and Beyond with Charlie Manson and the Family provides good insight into the personalities of Manson and the various Family members, as well as their life together.
