"When the polar ice caps melted, America's East Coast became an underwater graveyard--except for New York City. Today, a million people make their home among the skyscrapers poking through the ocean waves. A million people who like to live by their own rules--including Simone Pierce, one of the best private investigators in the city. It starts out as a routine surveillance job: cheating husband, attractive blonde. Something feels off, though, and when the husband turns up floating in the water with a hole in him, the cops like Simone for the murder. If she can just find the blonde, she'll clear her name, but instead she stumbles onto a strange network of power brokers and art collectors, all looking for a treasure that can't possibly exist. As she struggles to find the murderer, Simone is only sure of one thing: she can't trust anybody, not even herself, because the city she grew up in might have more secrets that even she knows." -- From dust jacket.
