Con or Bust (a fund for diversifying science fiction conventions) is auctioning off a copy of new book Steven Gould's new book, Impulse (an awesome, read-in-one-day adventure). Not only is this a signed hard-back, but if the bids go high enough, Gould will throw in an appearance in his next book, complete with "[being killed] in a spectacular or embarrassing way, if desired". You can place your bids here.
