In near-future Southeast Portland, Scout has survived three winters as a stray — a brown-and-white Labrador and Beagle mix with a crooked front leg and one ear that never stood up. For two years he has waited at the back door of Patterson's Corner Mart, where seventy-two-year-old Mrs. Patterson sets out a red bowl of leftovers every evening at six. He understands her loneliness, her grief for a dead husband, and the slow bleed of her failing store — but as a stray dog, he has no words.
When Multnomah County Animal Services picks him up, Scout lands in a shelter reeking of bleach. There, an orange cat named Chester — who has been watching Scout for months — presses a stolen experimental SL-3 neural chip into his paw. The implant is an unauthorized Nexum Corp "Savant" model. Within hours, Scout wakes with human-level intelligence, a reading vocabulary, and access to a hidden data stream no corporation wants him to see.
Chester reveals the truth: he is building the Underground, a secret network of chipped animals communicating beyond Nexum's surveillance. An Irish Wolfhound named Nala teaches Scout to mask his signal. A Siamese cat named Iris, dead before the story opens, left a backdoor into Nexum's entire firmware. Scout is now a Granted — and a target.
Mrs. Patterson adopts him. At home above the store, Scout faces the hardest test of his new mind: pretending to be an ordinary dog. He watches her add the same column three times and get it wrong. He learns the neighborhood's quiet tragedies — the bake-sale flyer for a child's leukemia, the graffiti that is really a friendship. And he discovers the smiling billboard across the street belongs to Brock Harrison, a developer who has made seventeen lowball offers on the store's land and is quietly choking Mrs. Patterson out of business.
Using the chip, Scout pulls property records, corporate filings, and zoning maps. He learns the land is owned free and clear, that Harrison's company is drowning in debt, and that the "final offer" is less than half the assessed value. The stray's secret becomes a plan — not to speak, but to protect. He nudges a Snickers bar toward a crying child. He "accidentally" helps Mrs. Patterson with her crossword. He becomes, quietly, the smartest resident on the block and the one person (or dog) who sees the whole picture.
A heartwarming, mysterious standalone story from the NeuroLink Universe — a series about what happens when the animals we love can finally speak.
