This novel was workshopped by the Cecil Street Irregulars, the Novelettes and the Gibraltar Point gang, and received excellent feedback from the first readers on the est-preview list (especially Pat York). Likewise, I'm indebted to all the people who read and commented on this book along the way. Thanks go to my editor, Patrick Nielsen Hayden, for reading this so quickly -- minutes after I finished it! Likewise to my agent, Don Maass, thank you. Thanks to Irene Gallo and Shelley Eshkar for knocking *two* out of the park with their cover-designs for my books. Thanks to my co-editors at Boing Boing and all the collaborators I've written with, who've made me a better writer. Thanks, I suppose, to the villains in my life, who inspired me to write this book rather than do something ugly that I'd regret. Thanks to Paul Boutin for commissioning the *Wired* article of the same name. Thanks to the readers and bloggers and Tribespeople who cared enough to check out my first book and liked it enough to check out this one.
