A brace of bumptious literary parties last night: the first, in Clerkenwell, for a new children's imprint that will publish books for children and young adults. It is helmed by Sarah Odedina (who was my first editor at Bloomsbury), and looks set to publish its first book later next year, which I look forward to very much indeed. Lots of little mince pies and bucketfulls of champagne made a merry evening in their snazzy, white-painted and wood-floored offices. I spotted The Fool's Girl author Celia Rees, who's got a new, modern-day novel coming out soon, as well as I, Coriander writer Sally Gardner. The place was thrumming with agents and authors as I left, so it all looks set for a rocket-fuelled lift off - very best of luck to Hot Key.
