Dani, a data analyst with an elite security firm, possesses the unnerving ability to read people by the trash they leave behind. Receipts, parking tickets, the detritus of daily life—if you leave it behind, she will figure you out. Her latest case involves high-tech industrial espionage at a corporation with ties to the military. But when a team of assassins sweeps through the firm, stealing all files and killing her coworkers, Dani narrowly escapes. Whoever ordered the strike thinks Dani has vital information and they put a hit man named Booker on her trail. Armed with only her wits and a bag of random investigation materials, Dani must figure out who the enemy really is while playing a high-stakes game of cat and mouse with the cunning hit man who has an agenda of his own.

Her narrow escape from blue-eyed assassin Tom Booker has made former data analyst Dani Britton question all of her choices—like trusting “good guys” who carry badges. On the run and haunted by the government-sanctioned massacre of her coworkers, Dani finally settles in remote Redemption Key, Florida, at a bar where strong drinks and shady deals are the norm. The bar owner, a local operator with a past of his own, gives Dani a job, no questions asked, and soon Dani’s ability to “read” the sketchy characters doing business at the bar proves invaluable. The libations flow, and the Key’s laid-back vibe and warm waters start doing their therapeutic work. But as the mercury rises, a twisted deal starts to go down—threatening to take Dani with it. Like sharks smelling blood, players on both sides of the law circle for the kill. And when charming apex predator Booker joins the frenzy, he may turn out to be the only one on Dani's side.
