Once Upon a Time in the North is a 2008 novella by Philip Pullman. The book serves as a prequel to Pullman's His Dark Materials trilogy. The premise of the story involves the meeting of Iorek Byrnison and Lee Scoresby: I've just finished a short book which will be coming out next spring, probably March or April in this country. It's called Once Upon A Time in the North, and it's about Lee and Iorek. When we see them for the first time with Lyra, Lee is not that old; he's fifty, sixty, something like that, so they know each other for a long time. But I wanted to write a story when they first met as they were young, and I've just written it. I'm making a little book like Lyra's Oxford. The Guardian carried an "exclusive" extract from the book under the heading Winds of Chance on 22 March 2008.The book launch took place on 31 March in Oxford during the Oxford Literary Festival.
