I love how the novel takes the cartographer's urge to measure and makes it human; "no one lacks a secret" becomes the legend on every page. The lines on Lina's charts are beautiful and merciless, a geometry of longing.
The science is not just set dressing: thermoclines feel like the emotional layers people refuse to mix, and Tideglass becomes a quiet confessional watched by strangers and ghosts. Jönköping's dusk softens nothing; it just makes edges gleam.
The narrator with a depth sounder steadies the voice, intimate and slightly haunted, promising a map while warning us about sonar shadows. I was electrified by how presence and absence keep trading places.
The boathouse at 2:14 a.m., the silver Saab, the locket, the SIM, the SJ case flecked with mussels: each object a coordinate that refuses to sit still on paper. Secrets don't flood here; they seep, colder than the lake.
I finished with chills, grateful for a book that lets knowledge be both lighthouse and fog. Five stars, no doubt.
