The Natural and the Artificial

"When priceless masterpieces vanish from elite museums, Special Agent Adrián Castillo, once the FBI's fiercest art hunter, is pulled back into a game he swore off. Seven years after a mysterious woman slipped through his hands during a deadly Met heist, a new theft in Paris bears her signature...and a message meant for him. A routine recovery spirals into a global conspiracy run by the Iscariot Brotherhood; an ancient, lethal network now wielding cutting-edge tech to rewrite cultural history. Forced from his desk and back into the field, Adrián finds himself hunted by assassins who know his past...and by a woman whose deadly grace and link to him defy reason. Each clue drags him deeper into a war between the natural and the artificial, where authenticity itself is under attack. Faced with a new rising star and an old trusted ally by his side, Adrián is left to confront the Brotherhood's most sinister secret. One connected to his past, his identity, and a power he's denied for so long. If he's to get the art back and put an end to the syndicate, he will have to become what he once feared...and unleash the wolf within. In a world built on deception, only what's real endures."
