The Subtle Knife
"His Dark Materials" is a trilogy consisting of "Northern Lights" (titled "The Golden Compass" in North America), "The Subtle Knife" and "The Amber Spyglass". "Northern Lights" won the Carnegie Medal for children's fiction in the UK in 1995. "The Amber Spyglass" was awarded both 2001 Whitbread Prize for best children's book and the Whitbread Book of the Year prize in January 2002, the first children's book to receive that award. The series won popular acclaim in late 2003, taking third place in the BBC's Big Read poll. Pullman has written two companion pieces to the trilogy, "Lyra's Oxford" and "Once Upon a Time in the North". He refers to a third, which will expand his character Will Parry, as the "green book".
