Beach life is killer, literally.

On the cusp of her high school graduation, Lily Harmony needs to figure out how to break it to her lawyer parents that she doesn't want to follow in the family footsteps-especially with her band in high demand on the Fort Myers beach scene. But when her father is killed inside his office and their mother accused of his murder, Lily and her estranged sister Annabelle are convinced the police have the wrong person. Clues are hard to come by until a mysterious man hands Lily a flash drive and warns her the information contained on it might get her killed.

As Lily works to unravel what the files and pictures mean, a stunning discovery reveals the murderer might be closer than she thought.

With the help of her gamer BFF and a drone named Felix, Lily and her sister scour the Everglades for connections to her father's killer. But what they find hidden in the canopy of cypress tress is more dangerous than they ever imagined-a long-lost secret worth millions-and worth killing for.
