If I spend thousands of dollars and fly halfway across the world to go to a book signing, what can I expect? I've never been to one before, and likely never will again. But Stormfather take me if this doesn't seem like a once in a lifetime opportunity.
You are more than welcome to come! But I do always feel a little strange when people spend a lot of money to come see me, as I'm not convinced I'm worth it.
Here's how a signing goes down: I usually speak for about an hour, which is divided into three segments. I generally start with a short (15 min or so) talk about something I'm interested in at the moment. Usually it relates to the book somehow, or to the fantasy genre. Then I do a Q&A with the audience for maybe 25 min. Then I do a reading for maybe 20 min. (This is usually from something I'm working on that isn't yet published.)
From there, I sit down and start doing the signing. This part takes a long time--four to six hours, depending. You usually get a line number from the store based on a couple of factors. (When you arrived and if/when you bought your book.) I strongly suggest checking with the store you plan to visit, as some of them have stricter policies than others about being required to buy a copy of the book to get into line. (Most of them don't require it, but let the people who bought the book from them--which is most people there--go first.)
You get maybe thirty seconds or so with me, during which you can ask a question and get a picture, if you want. (I always feel bad it's such a short time.) I will generally personalize up to three books, though I will sign as many as you want. Most stores only sell the US edition in the US.
If you mention you came from New Zealand, you will most likely be the person who came the longest distance, which I usually reward with a little pin.
All of these signings will be relatively packed, I'm afraid, so I can't suggest one over another being faster. But they're also all very good stores, and are generally willing to let you leave and grab food, then come back closer to your chance to get a book signed.
