Detective Cassidy Tremaine is young, attractive and a divorced mother of two. Driven and competitive, she has replaced all thoughts of romance with a near single-minded devotion to her career; a mindset shaped by her ex-husband's infidelity. Her heart hardened by the belief that no man can live up to her expectation, she spends much of her spare time trying to be the best detective in the NYPD. Six months in with a new robbery-homicide partner, she gets the case of a lifetime. Nine discarded corpses are found in the Staten Island Greenbelt parkland. How they died becomes an investigation in and of itself. The characteristics these victims once possessed seem to have three things in common: they were all young, they were all attractive, and they were all club hoppers. Recommendations from senior officials that Detective Tremaine give the case to a special investigative unit motivates her even more to unravel the mystery of the baffling murders. Shortly into the case of the Greenbelt 9, her attention latches onto a wealthy group of licentious late-night ne'er-do-wells with an unusual fetish for young attractive party goers, whom she begins to quietly investigate. A few days later, the case is suddenly resolved too neatly for Detective Tremaine to believe. Still curious about the strange group of wealthy loafers, Detective Tremaine chooses to infiltrate their society on her own. Not long into her association with the group, Detective Tremaine learns that she is being shadowed by a dark figure with eyes that reflect light and answers to the name Cristiãn. Her single-minded determination to discover which of her newfound acquaintances is the man with the glinting eyes leads her ever deeper into a world of erotic excesses and mind-bending experiences. Despite these deviances, the mounting clues convince her that she is on track to uncover the truth behind the Greenbelt 9 murders. And her greatest fear through it all is that she might be falling in love with the man of her dreams.
