Scott Landon book titles like The Coaster’s Daughter, Empty Devils, and Relics are all taken directly from the original novel, but you never really learn anything about their plots.
While it is made clear in the source material that Scott’s ideas come from the pool (“where we all go down to drink”), in the streaming series it’s interesting that Empty Devils is apparently about Boo’ya Moon.
Making this change allows Lisey the excuse of feeling like she has been caught up in her deceased husband’s imagination, which then in turn plays a key role in her denial that the magical world is real.
For the adaptation, however, Stephen King throws some interesting details at the audience – namely when Darla explains that Empty Devils is set at least partially in a world called Banilla where there is a monster guardian and waters that can heal and fascinate.
