The series, known collectively as His Dark Materials, centers on Lyra Belacqua, a preteen orphan who’s pursued by a murderous institution known as “the Magisterium.” Or to use the more familiar name, “the Holy Church.” In its quest to eradicate sin, the Church sanctions experiments involving the kidnap and torture of hundreds of children-experiments that separate body from soul and leave the children to stumble around zombie-like, and then die. Pullman’s books have sold 15 million copies worldwide, although it’s difficult to imagine adolescent novels any more openly subversive.
