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.
