I think you should behave exactly as usual and mention the book to new people as you introduce yourself, but only if asked about it to people whom you already know. If this was a US con I'd advise differently.

However, I have never known you be anything less than gracious. Naturally I consider that I conduct myself with the utmost decorum at all times and thus you should model yourself on me: if you want to be me, I will channel Ian Watson at the next convention, he can channel Tanith, and we can all pass our personalities on in this manner.
