A new installment of the “Left Behind” series is due out this week. “Over the last nine years, the ‘Left Behind’ series, which is based on Dr. Tim LaHaye’s literal, bloody interpretation of the Book of Revelation, has become one of the biggest surprise hits in American popular culture. The first 11 novels have sold more than 40 million copies. The authors have unseated John Grisham as the best-selling novelists for adults and, in some places where evangelical Christians are common, the books rival the Harry Potter series in sales.”
