But the VERY VERY EXCITING thing is that English sample translations of all six German Book Prize contenders are now online at New Books in German. Please take the rest of the day off work and read them all. They are by Martin Chalmers, Iain Galbraith, me, Zaia Alexander, Kári Driscoll and Alexandra Roesch. So obviously you should start with the Clemens Meyer one.
And seeing as you happen to be a publishing type with a large budget at your disposal, you could also enquire about buying translation rights, now that you too have fallen for Im Stein.
