The Disappearance of Sloane Sullivan

I’m curious how the author developed the backstory and what motivated choosing this particular event as the story’s core. Did the idea evolve from real events or pure imagination?

The narrative kept me questioning what was real and what was manipulated. I wonder if others felt the same uncertainty about her motives and truthfulness.

The pacing kept me on edge but also made me feel for the characters. I’d love to know whether this balance was intentional from the start or something that developed during writing.
