What if you saw something? Something heinous. Something the police have no clue about, but should? Kyra knows she's seen the killer. Actually seen him walking around the Slip Mire before and after his kills. She needs to get her information to the cops. She kissed Det.

But not sharing her information means she'll have blood on her hands when the killer strikes again. Gabe has his own problems. Dealing with the anniversary of his brother's disappearance is stressful enough. Now the brass is pressuring him to find the mysterious woman who gave him information that saved many lives. The woman who seems to be a walking chameleon. And kissed him in a dark alley weeks before. Meanwhile, a clandestine gathering is happening at the dark heart of the city. When Kyra investigates, she finds a gyre of depravity and evil. Kyra and Gabe will face that depravity head on. If they don't learn to trust one another, it may just swallow them whole. Fans of dark urban crime fiction, mysterious serial killers, and a splash of the horrific won't be able to put this one down.
