When singer Alessandra Moreau is found brutally murdered in New York State Senator Leigh Drayman's living room, NYPD Detectives Chiara Corelli and P.J. Parker are thrust into another high-stakes investigation. The victim, a rising star, harbored a closely guarded secret shared with only three people. She was transgender--just like the senator.

What begins as a focused investigation into three suspects explodes into something far more sinister when thirteen identical murders of trans women surface from the past two years. As the body count rises, Corelli and Parker uncover two additional cold cases from nearly two decades ago that could hold the key.

But their quarry is clever, methodical, and has been hiding behind a perfect disguise for years. In a race against time, the detectives must unravel decades of deception before another woman dies.
