The Writing in the Water

The shifting viewpoints added layers to the mystery, but I wonder if that was planned from the start or developed during writing. Did it help build suspense or make it harder to follow?

The recurring imagery of water seemed to mirror the characters' submerged secrets. Was this intended to evoke a sense of inescapable truth or something else?

The mood is so immersive — I’d love to know if the author drew from personal experiences or crafted the environment purely from imagination.
