Best for readers who enjoy maritime settings and technical detail around audio research, plus a slow burn that favors atmosphere over twists. Content notes include drowning, stalking, data tampering, and professional gaslighting. Older teens and adults could handle it. If you need brisk momentum or a densely clued puzzle, this may feel more static than suspenseful.
Winter on Puget Sound. My name is Raya Ortega, and in a few short hours I'm set to stand in a lecture hall at the Pacific Maritime Institute and prove that my brother Luis didn't drown by accident. In a rented machine bay off Dock Street, my jury-rigged array of hydrophones and salvaged preamps is tuned to the Tacoma Narrows, ready to map the channel like a heartbeat, to pull a pattern out of water that everyone else calls noise. The committee is coming. So is the press. Despite the wreckage of this year, tonight is supposed to be the clean signal, the turn toward daylight.
There's just one problem: someone else has been listening longer than me. The data on my recorder has been spliced, the tides tables swapped, and a ferry deckhand named Lyle keeps showing up two steps ahead. If I run the demo, I'll light up more than a current—I'll ping a predator that knows my name. If I bail, the proof drowns with me and Luis stays a cautionary tale. The water is already moving, the hum under the bridge growing teeth, and if I'm not careful, the Narrows will take me exactly the way they took him.
