Rebecca Cantrell's meal and guests have a distinctly German theme. I, on the other hand, would probably go for sushi or a Thai meal as I so rarely get the chance to sample those cuisines. The guests, though? You're allowed three, and assuming they have to be people you don't actually know, I'd choose Viggo Mortensen, J. K. Rowling and Ian McEwan (that did not take long to decide!). I wouldn't need to do any talking, just listen (and, occasionally, watch of course.) Maybe you'd like to answer the dinner-guest question on your own blog or in the comments here.
The Criminal Minds blog/panel is well worth subscribing to if you don't know it already - as well as the themed posts you can also email questions to the seven authors, and it looks as if you can win prizes for writing good comments. It also reminds me that I've been meaning to try a novel by one of its bloggers, C. J. Lyons (great dinner companions!), as I like medical thrillers, so I'll add one to my list. (Currently running at about 500 books, and that's not counting the couple of hundred actual ones I have on my shelves waiting to be read.)
