Discovered at this late date here, in a post by her North American publisher. I'm actually more familiar with that prize program -- it's affiliated with the festival in Erlangen -- for its lifetime achievement award, which this year went to Ralf Konig. I don't know if that's similar to the big "The Reuben" and then a bunch of divisional NCS awards, or what -- but the one Lust one is right up there. I believe it shares the same prize money, if I'm looking at these site's correctly and seeing prize money.
The original posts notes that Lust's autobiographical work was also the winner of the LA Times Book Prize in its category and received an Ignatz.
