YMMV / Duma Key

  • Call Forward: If I recall correctly, Perse at one point is described as having a red spot/blob/mark on her forehead. This could very easily put the book into the Dark Tower pantheon, which would make Perse a minion of the Crimson King. Jerome harkens to the beam breakers. The three are, of course, a ka-tet.
  • Ho Yay: Wireman and Freemantle. Many times, but Wireman kissing his hand in particular.
  • Squick: When Gandalf gets hit by the car.
    • And if that doesn't do it for you, Edgars appetizing meal shortly afterword. Ugh.
