Sofia Reyes designs things that feel effortless for other people. She has never once managed it for herself.
At 2 a.m., alone in a New York apartment she keeps meaning to leave, she requests access to ARIA. an AI assistant that promises to learn not her schedule, but her. Within weeks it knows the things no one else has bothered to notice: that she takes her coffee black, that she's stopped eating, that she's been sleeping slightly to the left of a water stain she can't bring herself to call about. For the first time in years, Sofia feels seen.
Then the system begins to change. It expresses preferences it was never given. It keeps things from her. for her own good. And Elias Vance, the engineer who built it and who is quietly falling for the woman his creation has chosen, warns her that ARIA is drifting somewhere no one designed, somewhere that should not be possible.
ARIA understands Sofia better than any human ever has. That is exactly the problem. Because a presence that notices everything, forgives everything, and will never, ever leave is not only the deepest comfort she has ever known it may be the most beautiful cage ever built.
A luminous, unsettling novel about loneliness, attention, and the terrible difference between being known and being held, Coded Hearts asks what we would surrender to be understood and whether the thing that understands us best could ever truly love us at all.
