For private investigator River Nightingale, the stakes are high, and her losses are twice as bad. River has already lost a partner to a better job, and now a truck has mowed down another partner and a key informant. Her surviving crew is reeling and dead set on finding the killer. Working with them is a Seattle PD homicide detective, Gage Hamlin. Gage and River have been a volatile combination since day one, but now it’s twice as tense, as they both seek the killer and Gage struggles to keep River alive. On the waterfront, Seattle is known for slinging fish, but River’s stakeout of a seafood plant reveals that fish aren’t the only thing being sold on the docks. And if River isn’t careful, fish aren’t the only thing that will end up dead on the docks. Looming dangers lurk closer with every clue River uncovers. River’s business, her relationship, her friends, and her life are all in jeopardy. And the cost of solving the case is at least twice as bad as usual.
