Working for his mother, the sheriff of an idyllic Midwestern resort town, Eli North, when the body of a teenage boy is found in the lake, is drawn into an investigation related to America's opioid epidemic that becomes much more than just a hunt for a killer.

Eli North is not okay. His drinking is getting worse by the day, his emotional wounds after a deployment to Afghanistan are as raw as ever, his marriage and career are over, and the only job he can hold down is with the local sheriff's department. And that's only because the sheriff is his mother--and she's overwhelmed with small town Shaky Lake's dwindling budget and the fallout from the opioid epidemic. The Northwoods of Wisconsin may be a vacationer's paradise, but amidst the fishing trips and campfires and Paul Bunyan festivals, something sinister is taking shape. When the body of a teenage boy is found in the lake, it sets in motion an investigation that leads Eli to a wealthy enclave with a violent past, a pharmaceutical salesman, and a missing teenage girl. Soon, Eli and his mother, along with a young FBI agent, are on the hunt for more than just a killer. If Eli solves the case, could he finally get the shot at redemption he so desperately needs? Or will answers to this dark case elude him and continue to bring destruction to the Northwoods?
