Disciples by Benjamin Marra HC

Marin County, 1978. In this graphic novel, Clara and Wendy are two teens getting high one night alone at home. Before the night ends, they've disappeared - until five months later, when Clara is found, disheveled, in Death Valley National Park.
 
From Clara's mysterious reappearance in Death Valley, Disciples cuts to the present day, where stories of "The California Cult" and its enigmatic - and never-caught - leader, Billy Joe, are as much a part of the popular culture as the Manson Family. Clara, the lone survivor of the cult, has adopted a new identity to protect her and her daughter, Wren. And she mostly does, until one night when the past and present horrifically collide.
Disciples is a seamless collaboration between cartoonist Ben Marra and filmmakers David Birke and Nicholas McCarthy. Birke and McCarthy's script celebrates and reinvents a cult film ethos. It combines the best of 1970s era eerie-thriller-terror movies in a fresh and revelatory way, similar to how Marra has continued/reinvented the work of Abel Ferrara and George Cosmatos in graphic novels like Night Business.
