Ryan's main goal is to advocate for a new form of narratology: "Possible Worlds (PW) Theory." She advocates for this new theory by pointing out holes in adjacent theories that are typically used to dissect truth, fiction, narrators, plots, characters, and mimesis and diegesis. Chapters 1 - 6 address these concepts before she moves on to the potential applications of PW Theory in theoretical physics, current technology, narratology and transmedia, and future technology (such as AI) in the remaining 4 chapters.
When dissecting a new theory, there are thought experiments required to identify the highlights and pitfalls of the new ideology. Ryan is exceptional at identifying the weaknesses and strengths of her ideas, along with how PW Theory can blend with existing theories to try to fill the gap identified by science and technology. For anyone interested in narrative structure and ways to analyze reader thoughts, reactions, and contexts from the perspective of a writer or scholar, this could be a beneficial text if you can wade through the dense scholarly language reminiscent of the writings of Judith Butler.
