I've been reading "IT" and one of the Protagonists keeps talking about a Turtle and how it's guiding him to safety.
I've also heard from a source that "Hearts in Atlantis" has almost an entire page that speaks of the Crimson King, the Tower, and, Gunslingers. Needless to say "I have no shame in admitting this" Anytime I hear Gunslinger I get a semi hard on waiting for their badass tale.
