His Dark Materials (novel and adaptations)

His Dark Materials is a fantasy trilogy by Philip Pullman, consisting of "Northern Lights" (also known as "The Golden Compass"), "The Subtle Knife," and "The Amber Spyglass." It follows a young girl named Lyra Belacqua as she explores parallel worlds, battles oppressive forces, and uncovers deep truths about existence and consciousness. The story weaves themes of free will, the nature of the soul (represented by daemons, animal manifestations of characters' inner selves), and the clash between science and religion. Adaptations include a popular film in 2007 and an acclaimed HBO/BBC television series launched in 2019, which expands on the intricate narrative.
