In California, Jim Jones even staged a shooting of himself. The lesson of this was two-fold. One, that he was a god - he could heal himself. He had these magic powers. A large segment of his congregation came from a Pentecostal tradition that believed in faith healing and already believed Jones had the power to cure others. And two, the "shooting" made him seem important. Civil rights leaders were being gunned down - MLK, Jr., Medgar Evers, Malcolm X - and he longed to be considered as heroic and important as they were.

That's why I think it's important to revisit the story of Jonestown. I hope readers come away with a greater compassion for Jim Jones's victims, a third of whom were minors. To get a feeling for what it was like to be in their situation.

Escuela Caribe preyed upon parents' fears of secular culture to recruit students. Parents could send their kids to a place where they'd be sheltered from evil secular influences - sex, drugs, alcohol, and a questioning mentality. A place where children would be forced to become good little clones of their parents.

My parents subscribed to both Time and Newsweek and in 1978, I remember the covers of both that December were of the bodies in the jungle. The fact that many of the people who drank the cyanide - as well as Jim Jones himself - were originally from Indiana, that stayed with me. I wanted to know why they did such a baffling, horrendous thing, why they would kill their children.

What better way to control your kid than by sending her to a compound on an island in the middle of the Caribbean, confiscating her money and passport, where she will be forced to comply with the program if she wants to leave?

I was pregnant with my youngest child at the time, writing about mass death while I'm growing this precious little life inside me. Here I am, worried about everything I eat and drink and whether I walk past a smoker, and meanwhile I'm writing about an event where almost three hundred children were slaughtered. Most were never identified and are buried in a mass grave in Oakland. It was surreal. But it felt good to give Jim Jones's victims a voice, especially ordinary church members.

I was working on a satirical novel about a charismatic preacher who takes over a small Indiana town. Then I remembered Jim Jones was from Indiana and Googled him. I learned that the FBI had recently released all the documents that agents collected from Jonestown after the massacre - over 50,000 pieces of paper and almost 1,000 audio tapes. I started reading the files and couldn't tear myself away; I find "true" stories inherently more powerful than fiction.
