The Dissonant Chord

Lisbon is not just a city-it's an architecture of control. Detective Morrisson Kane has spent his life believing in evidence, logic, and the law. But when a series of impossible deaths leave behind a recurring symbol of a bat's wing, Kane finds himself chasing a shadow that leaves no fingerprints, no motives, and no mistakes. At the center of the web is Ricky, a talented musician whose life has been built on a foundation of silence.
When a chilling DNA match connects him to an unknown, lethal sister-Renata-the truth about his past unravels. He wasn't just a survivor of a childhood fire; he was the primary instrument in a grand, invisible design.
