When a city councilman's murder exposes a multi-state environmental fraud conspiracy, former lawyer Mackenzie O'Brien must risk everything to protect her community's water supply.

Mac thought her biggest challenge would be hosting Hopefield's biggest New Year's Eve celebration at her Emerald Isle Brewery. Instead, councilman Nathan Bradshaw turns up dead in her office during the midnight countdown, and Mac discovers that someone has been systematically manipulating environmental reports to benefit corrupt developers.

Armed with her legal expertise and brewing partner Travis Blake's chemistry knowledge, Mac uncovers a conspiracy that threatens water quality across the Southeast. But when the investigation reveals that Clean Water Solutions has been bribing local officials and murdering whistleblowers, Mac realizes the killer has both the scientific expertise to create untraceable poisons and the desperate motive to eliminate anyone who threatens their operation.

In small-town Hopefield, North Carolina, environmental protection becomes a matter of life and death.

With Police Chief Alexa Carlsbad coordinating the investigation and state environmental agents closing in, Mac must expose a corporate conspiracy before more people die. But when the killer is someone she trusts, and Clean Water Solutions has millions of dollars at stake, solving this murder might cost Mac her life—and her chance at happiness with Travis.
