Join me today for a Twitter chat with contributors to The Mad Scientist’s Guide to World Domination. Here’s the press release from Tor:

This Wednesday, February 20, at 4 PM EST #TorChat is taking you behind the scenes in some very dangerous places—the minds of several mad scientists. Joining readers will be the mistress of time travel and author of the New York Times bestselling Outlander novels, Diana Gabaldon; the creator of Soon I Will Be Invincible’s Doctor Impossible, Austin Grossman; and creative genius (and by that, we mean mad scientist) Seanan McGuire, the author of the October Daye series, as well as the Newsflesh Trilogy (as Mira Grant). Together, they’ll be discussing the perfect layout to the underground lair, how to perfect your evil laugh, and, of course, the best way to try to take over the world!

The chat will be loosely moderated by editor extraordinaire and mad scientist wrangler John Joseph Adams, a fanastic anthologist, editor, and the publisher of Lightspeed Magazine. We hope all you budding evil geniuses will follow the chat and join in using the Twitter hashtag #TorChat!
