Perfect for you if...

You love thrillers with a strong operational edge, where the protagonist's military or professional skills actually matter to solving the plot.
You enjoy character-driven mysteries set in vivid locations like the Florida Keys, where the setting feels like another character.
You appreciate stories that balance high stakes with genuine warmth between found-family crews, not just relentless darkness.

Maybe not for you if...

You prefer psychological twists and unreliable narrators over straightforward missing-person mysteries with clear antagonists.
You want literary complexity and moral ambiguity rather than a competent hero who knows how to get things done.
You're looking for romance as the primary plot; the romantic subplot here is secondary to the action.

About this book

Former Blackhawk pilot Luke Angel has settled into a quiet life in coastal Florida, running a seaplane business with his loyal crew and well-trained dog. When a plane belonging to a friend disappears from his airport, local detectives struggle to find answers. With clues scattered across the Keys and the Gulf of Mexico, Luke may be the only person with the connections needed to solve the mystery. The investigation forces Luke to confront old family tensions and his past relationship with a woman he once loved. When his eleven-year-old niece becomes caught up in the danger, Luke faces threats from people determined to stop him. He must act quickly to protect those close to him, or risk losing everything.
