I'm one of the guests of honour at this year's Picocon (which is number 32), alongside three great writers -- Frances Hardinge, Ian MacDonald and Cory Doctorow., at Imperial College, London. I'm delighted to be asked -- it's the second time I'm been one of their guests and I'm glad I was interesting enough last time that they wanted me back. It's one of my favourite cons: it's run by the members of the Imperial College Science Fiction and Fantasy Society, who are mostly students and they put on wonderfully imaginative, entertaining programmes. I came up through student sf societies and university-based cons, and going to Picocon is like going back to my roots.
