Requested by @mhawkeyem! Off the top of my head...
  1. Venice
    Because of Donna Leon. It's entirely her fault.
  2. Southern Sweden
    I want to take tours of the locations from Henning Mankell and Camilla Läckberg's books.
  3. Boston
    I've read about 92 books set in Boston, but I've never been there! I want to see all the historic sites for myself.
  4. Virginia
    This one is a two-fer. I want to find Cabeswater (à la Maggie Stiefvater's Raven Cycle). And I want to visit Williamsburg (because of Elswyth Thane's Williamsburg novels).
  5. London
    I've been to London, but my last trip to England was in 2003. And I've discovered so many great authors since then! Elizabeth George, Deborah Crombie, JK Rowling (yes, yes I was late to the game), Robert Galbraith, Kate Morton, Lisa Jewell, and so many more! Pretty sure I'll need at least a month there to pay a proper pilgrimage.
