I must apologize – I've known this for ages and keep forgetting to share. The Harvill Secker Young Translators' Prize goes to a translator under a certain age from a particular language who submits the most impressive version of a particular original. And this year it was awarded for a translation from German of a very tricky story by Julia Franck, and you can read winner Eleanor Collins' lovely version at the Granta website.
Collins receives a big fat cheque and a mentorship with top translator Shaun Whiteside and a pile of books. Belated congratulations!
