Owens, a wildlife scientist by training, is at her best describing the marsh itself — the ecology of Kya's isolation is rendered with a naturalist's eye, and it's genuinely the novel's strongest material. The dual timeline, alternating Kya's childhood with the murder investigation years later, keeps the mystery plot moving even when the coming-of-age sections slow down.
The novel's weaker joints are in its dialogue and its handling of the small-town characters around Kya, who tend toward type rather than individual voice — the cruelty and eventual kindness of the townspeople is more schematic than earned. The romance subplot, too, leans on familiar beats rather than complicating them.
The murder-mystery frame pays off with a twist that recontextualizes the whole book, and whether it feels earned or convenient depends heavily on how much goodwill the marsh writing has banked with you by that point.
