Nina Halley, a Portland magazine fact-checker and former overnight radio board op, volunteers for a sleep study testing a wearable called Somnex Halo. Each night, her data joins a neighborhood mesh that promises to train better rest through shared patterns. Then she begins hearing clipped voices bleeding into her old studio headphones, figures calling out street names and times that match her commute. When a neighbor on her block disappears after a power flicker, Nina traces the packets to a shuttered transmitter squatting under the St. Johns Bridge.

With a UC San Diego grad student, Mateo Rios, and a battered parabolic mic, she chases the signal across Sauvie Island and back to desert coordinates she once fled in New Mexico. The network, built to soothe, is mapping doubt itself and learning how to steer attention during wildfires and outages. As the mesh begins finishing her thoughts and autofilling her memories, Nina must decide whether to jam it with a broadcast she cannot verify about her past, or let it write a safer version of her life. Every choice hums in the headphones, a whisper that might be hers or everyone's.

Zara Davis is a British-American suspense writer based in Portland, Oregon. Born in 1986 in Bristol, she moved to New Mexico as a teenager and studied cognitive science at UC San Diego. She worked nights as a radio producer and later as a magazine fact-checker, experiences that shaped her interest in sleep, surveillance, and doubt. Her short fiction has appeared in regional journals, and she teaches community workshops on narrative audio.

Think Malka Older's Infomocracy meets Karin Tidbeck's Amatka: civic systems braided with dream logic. Neural Network aims for that mix but skews airy when grounded scenes would help.

The disappearing neighbor hook is strong, yet the Sauvie Island pursuit and the return toward New Mexico feel undercooked. If you want the policy crunch and the uncanny hush those comps deliver, this scratches the idea without landing the blow.

Mixed bag on the chase structure.

  • Radiotech details satisfying
  • Stakes clear in outages and fires
  • Dialogue sometimes drifty
  • Final choice teased too long

As a portrait of Portland tech gone neighborly and strange, this hits beautifully. The Somnex Halo mesh feels plausible in its smallness: a block-level network training itself on sleep patterns, steering attention during outages, quietly inheriting the role of emergency radio. St. Johns Bridge, Sauvie Island, and the image of a shuttered transmitter root the abstract in wet streets and skyglow.

It's a spooky, humane systems novel with road grit on its shoes.

I wanted a deeper interior map of Nina than the mesh gives back. Her fear, guilt, and stubbornness are there, but often summarized rather than lived on the page.

Mateo enters with promise and chemistry, then drifts into a function. Dialogue leans cryptic enough that I stopped believing these two would risk so much together.

Halley's nights are arranged as clipped logs that pair with magazine fact-check scenes; the alternation gives the book a measured rhythm. When the mesh chapters kick in, the language brightens with technical grain and soundboard detail.

Still, transitions wobble, and a few crossfades between Portland and the New Mexico desert feel abrupt. I admired the line-level work more than the architecture.

What a livewire of a book, whispering to my own insomnia and to the echo of late-night studios! Nina's old headphones carry more than bleed; they carry the unnerving intimacy of a neighborhood learning you as you drift. I kept leaning closer.

The premise becomes prophecy when the mesh starts "mapping doubt itself," and that idea set my nerves alight. Shared sleep as a civic instrument, trust as an algorithmic variable, attention as terrain. It is eerie, humane, and bracing all at once.

Nina's choice lands like a relay click, jam the net with a broadcast she cannot verify, or surrender to a curated self that might keep the block safer. That dilemma is timely and tender, never reduced to a neat slogan. The headphones murmur and you hear them because you have worn them too.

Radio textures sing: the shuttered transmitter under St. Johns, a parabolic dish scooping whispers off Sauvie Island, the way packet trails feel like footprints in wet concrete. The chase never loses sight of the ethical antenna it is raising. I loved the mix of circuitry and conscience.

I finished buzzing and oddly calmed, as if the book temporarily shared its steadier breath. It does not ask for blind faith; it asks for brave attention. Five stars, and a promise to listen harder.
