Will there be anymore books in his dark materials?

The "His Dark Materials" trilogy includes the novels "Northern Lights" (published in the US as "The Golden Compass"), "The Subtle Knife" and "The Amber Spyglass". There are two spin-off titles currently available, entitled "Once Upon a Time in the North" and "Lyra's Oxford.

Philip Pullman has said that he will be writing a small green book, about the character Will. "Lyras Oxford was a dark red book. Once Upon a Time in the North will be a dark Blue book. There still remains a green book. And that will be Will's book. Eventually..."

The Book of Dust, set in the His Dark Materials universe, is also set to be published in the future. Pullman currently says that the book will feature Lyra as a main character.
