Have you seen that some authors are charging book clubs high fees to come to talk with them? If your book club is discussing Empty Mansions, arrange for one of the authors to meet with your group in person or via phone or Skype -- for free. Send an email to Bill Dedman. (Let us know the date and time, and we'll work it out to be there in person or via Skype.)
More info is on our page for book clubs.
