Query: give us more Pullman!

Philip Pullman must have been possessed by some spiritual power when he wrote his Dark Materials. Dust. Angels. Spectres. Zombies. Doorways into other worlds. Trepanning. Bloodmoss. Witches. The Great War of Good and Evil. The compass. The subtle knife. Pantalaimon, Lyra and Will. It is only Philip Pullman who can pull off integrating all these ideas and symbols in one excellent book, and keep us muddled as to who fall under the forces of Good, and who fall under the forces of Evil. The Subtle Knife is certainly not a disappointment after the magic of The Golden Compass. He skillfully weaves the lives of Lyra and Will together through a spell-binding storytelling of loyalty, fate, fear and friendship. And as he leaves us hanging once more at the end, we fear for their lives, and hold our breaths at the thought that they just might do each other in!
