Dr. Mara Sato came to the edge of known space to do one thing: map an alien city everyone swears is dead.She's the best xenoarchaeologist Earth has, a scientist with a reputation for turning impossibilities into data. She's also a widow who learned the hard way what institutions do to people they can't control. So when Earth's diplomats attach a "security liaison" to her mission and rush her toward a treaty deadline, Mara keeps her focus on the ruins and her rules: no theft, no coercion, no lies.Then the city responds.Doors re-form under her palm. Corridors shift like they're thinking. And in the shadow of black-glass arches, Mara realizes the truth the briefings buried: the ruins aren't abandoned. They're guarded.Kael'Ryn is the alien diplomat assigned to contain the human expedition. Controlled, lethal when he needs to be, and bound by a duty he won't explain, he lays down strict terms for entry into the Silent City. Mara should hate him for it. Instead, she can't stop noticing how carefully he keeps everyone alive, how much restraint it takes, and how the city seems to... listen when he speaks.When every translation attempt collapses into static, Kael offers the only method that works: a resonance protocol that synchronizes breath, pulse, and proximity to bridge two species' languages. It's clinical. Consent-forward. Necessary.And it's intimate enough to become political ammunition.As Mara and Kael unlock chambers no one else can access, their connection turns into the most dangerous variable on the planet. A human operative leaks footage of their "work" as scandal. An alien faction brands Kael a traitor. The treaty clock ticks down while sabotage pushes the living city toward waking defenses no one can stop.Then the city delivers its verdict: no agreement between worlds will stand unless it is witnessed as true by a bonded pair.To save their people, Mara and Kael must choose trust under surveillance, claim their partnership in the open, and step into the heart of a living ruin that judges intention itself-before fear and ambition turn first contact into war.The Living Ruins is a first contact sci-fi romance packed with living-planet mystery, diplomatic brinkmanship, forced proximity, and high-heat chemistry (non-explicit), featuring a mature, brilliant heroine and an honor-bound alien diplomat whose restraint is the most dangerous thing about him.
