The Sunday Times best-selling author of Closer Than You Think returns with a breathtaking new novel in the Cincinnati series - would you cross the line between danger and desire, and justice and revenge? A desperate hunt to find a young girl's killer is about to turn deadly....

Former army ranger Marcus O'Bannion and homicide cop Scarlett Bishop have met only briefly, but when Scarlett receives a phone call in the middle of the night, she immediately recognises the smooth voice asking her to meet him in one of Cincinnati's roughest areas.

On arriving, Scarlett finds the body of a teenage Asian girl and Marcus injured. Marcus claims the young woman was working for an affluent local family, and the last time he saw her she was terrified and clearly in need of help.

Having agreed to meet her, they were both targeted for death. As they investigate, Scarlett and Marcus are pulled into the dangerous world of human trafficking, where they soon realise they are going to have to become as ruthless as those they are hunting. Because if they don't, how many other girls may end up alone in the dark?
