When heritage conservator Anelise Puhl is hired to assess Curitiba’s abandoned Estação Aurora before its redevelopment, she expects structural problems—not a buried secret someone is willing to kill to protect. Then she discovers evidence that the station’s infamous 1989 accident was never the tragedy everyone believed. Old plans contradict official records, sealed rooms have been disturbed, and someone is quietly destroying anything that could reveal what really happened. Her investigation puts her directly against Vicente Krieger, the controlled structural engineer overseeing the project—and heir to the family whose name appears throughout the station’s history. Vicente wants Anelise to stop digging. Anelise refuses to trust a man who keeps answering her questions with silence. But as danger closes in, their professional rivalry becomes an attraction neither can ignore. The deeper they dig, the more personal the mystery becomes. Because the truth connecting their families has been buried for decades. And someone is determined to make sure it stays buried.
