From bestselling author Mike Lawson comes the latest installment in the award-winning Joe DeMarco series.

As a fixer for influential congressman John Mahoney in Washington, DC, Joe DeMarco has found himself in plenty of unexpected and dangerous situations. In House Rivals, DeMarco is taken further out of his element than ever before, sent to North Dakota to protect a passionate but naïve twenty-two-year-old blogger who has put herself in harm’s way.

The young woman is Sarah Johnson, whose grandfather saved Mahoney’s life in Vietnam. For the past two years, Sarah has been on a relentless crusade against a billionaire oil tycoon who has profited handsomely from the natural gas boom in the Dakotas—and who she believes has been bribing small-time politicians and judges to keep things in his favor. Though she has no hard evidence against the man, Sarah has been assaulted and received death threats for her meddling. DeMarco, given his years of experience bending the rules in DC, suspects that a middleman like himself is pulling strings for the tycoon. But as DeMarco tries to identify his adversaries, the situation turns unexpectedly violent, and DeMarco finds himself in a battle of wits against two ruthless problem solvers who will stop at nothing to win.
