Only the Stairwell Knows. Cindermath, #4

When a storm locks two strangers inside a tower of glass, desire becomes more dangerous than the hurricane outside. High above Miami's coastline, Halocline Tower was built to withstand almost anything-except what happens when the world below drowns in chaos. As a Category-5 hurricane slams the city, the elevators shut down, the power falters, and the stairwells echo with the groan of wind-driven glass.
In the penthouse, two people who have never met find themselves trapped together with no way out. Keir Navarre, a former structural engineer turned property investor, knows the building's bones better than anyone. He trusts protocols, pressure gauges, and his own hands to keep the glass walls from giving way. Isla Serrano, an interior and lighting designer, believes in atmosphere, comfort, and human connection.
When the storm cuts them off from the world, their survival depends on both: his systems, her senses. But fear sparks heat. Every blackout, every shudder of the tower, every crash of thunder outside drives them closer, until attraction becomes inescapable. What begins as hesitant touches and whispered reassurances ignites into an escalating fire-slow burn giving way to fevered urgency, tenderness colliding with raw intensity.
As the storm rages louder, so do they. This is not just romance. This is Stormpulse Romance (SPR)-a bold new subgenre where erotic heat and survival thriller collide. Each external disaster beat-shattered glass, flooding rain, the flicker of emergency lights-fuels the intimate intensity inside. The hurricane is more than backdrop: it is heartbeat, pressure, catalyst. For twelve cinematic episodes, the story builds like the storm itself: calm, disruption, escalation, climax, and release.
By the time rescue lights cut through the dawn, Keir and Isla have already survived the greatest storm of all-the one that stripped them bare, body and soul. Only the Stairwell Knows is a pulse-racing, high-heat, single-location romance unlike anything you've read before. Written with cinematic pacing, emotionally charged prose, and an intensity that refuses to fade to black, it delivers the ultimate promise: when the outer storm ends, the inner storm finds peace.
Perfect for readers of dark, sensual romance and high-stakes thrillers-this novel defines a brand-new frontier in commercial fiction. Stormpulse Romance is here. And once you step inside, you won't be able to put it down until the final surge subsides.---
