I've just confirmed that I will be appearing at Nine Worlds Geekfest on the 10th and 11th of August. This looks like a great event, run by and for SFF fans and with something for everyone. And they're currently running a kickstarter project which lets early supporters get cheap tickets.
In other and unrelated news, Tor are re-releasing the marvellous Saga of the Exiles, and they have asked several SF authors (myself included) why we loved these books. You can read all about that here.
