As the novel moves between the three settings, the characters' fates converge, and the line between the author writing them and the worlds being written collapses. It is a concrete test case for any claim that an author stands outside and above her fiction.
The act of writing does more than describe separate worlds. It is the mechanism that joins them, so realities with no physical link become connected because one consciousness narrates them together. On this view, narration is causal rather than merely representational: whoever tells the story creates the channel through which worlds touch.
Stories passed down by a grandmother figure look like simple fables, but they encode real cosmological and historical knowledge. The disguise protects that knowledge and lets it cross generations, and even worlds, until someone is ready to decode it. The unassuming form of a folk tale is what allows dangerous or vast truths to survive transmission.
When the same mythic figures and patterns appear on an alien planet, in a Celtic-style fairy realm, and in a Caribbean writer's imagination, the repetition can be read as a clue rather than a coincidence. It suggests a common underlying source. Seen through this lens, cross-cultural parallels in myth become traces of hidden connection instead of independent invention.
