Here's the link to the longlist. Twenty titles, nine of which aren't available in the shops quite yet. I've only read three of them, two of which I vehemently disliked. So my fave so far is easily Karen Duve's Taxi - which I absolutely loved.
The brochure with extracts from all the longlisted titles is available for free in bookshops from Saturday. The shortlist will be announced on 17 September, and translations of those extracts will no doubt be available online somewhere or other. The winner is announced at the Frankfurt Book Fair on 13 October.
