On April 3rd, 1990, Jack and Molly Went's two-year-old daughter Sammy disappeared from their Kentucky home. Already estranged since the girl's birth, the couple drifted apart, with Jack raising their other children as part of the Church of the Light Within, a Pentecostal fundamentalist group who handle poisonous snakes as part of their worship. Years later, Australian teacher Kimberly Leamy is told that she may be Sammy Went. Kim travels to America to reunite with a family she never knew she had, and to uncover the secret behind her abduction—a mystery that will take her deep into the dark heart of a cult where she must fight for her life against those determined to save her soul.
