To mark the release of Betrayal, the starwars_eu LiveJournal community is sponsoring an IRC chat on Holonet.org this Tuesday night.
This is live, free, and open to absolutely everyone. The purpose: to discuss the book with your fellow fans, in real time. Nothing more, nothing less.
That's this Tuesday, 30th May, starting at 8pm Eastern, 5pm Pacific, Midnight UTC, and 1am British Summer Time.
It's on irc.holonet.org, channel #eu, and if IRC sounds a little intimidating, you can use Holonet's own straightforward web-based chat client, which I'm told works best on the Firefox browser.
