Detective Sergeant Sam Holland has a chance to redeem her career when she is assigned to investigate a senator's murder, but when she is teamed up with a former fling, she must separate her reignited passions from the case at hand.

Washington, D.C., Metro Police Detective Sergeant Sam Holland needs a big win to salvage her career—and her confidence—after a disastrous investigation. The perfect opportunity arises when Senator John O’Connor is found brutally murdered in his bed, and Sam is assigned to the case. Things get complicated when Sam has to team up with Nick Cappuano, O’Connor’s friend and chief of staff…and the man Sam had a memorable one-night stand with years earlier. Their sexual chemistry still sizzles, and Sam has to fight to stay focused on the case. Sleeping with a material witness is another mistake she can’t afford—especially when the bodies keep piling up.

Standing over the body of a Supreme Court nominee, Lieutenant Sam Holland is hip-deep in another high-profile murder case. That she was one of the last people to see Julian Sinclair alive only complicates things even more. With her relationship with Senator Nick Cappuano heating up, they’re attracting a lot of unwanted media attention and blinding flashbulbs. The pressure is on for Sam to find Sinclair’s killer, but a new lead in her father’s unsolved shooting puts her in unexpected danger. When long-buried secrets threaten to derail her relationship with Nick, Sam realizes that while justice can be blind, mixing romance with politics has the potential to be fatal.

A deadly serious affair… The story breaks as Metro PD lieutenant Sam Holland attends a dinner party with her husband, Vice President Nick Cappuano: President Nelson is accused of having an affair. More shocking still, campaign staffer Tara Weber claims the president fathered her newborn son—while the First Lady was undergoing secret cancer treatment. When a high-profile murder case hits Sam’s desk, she’s shocked to uncover a connection to the presidential scandal. With the department caught up in its own internal scandals, and the chief’s job hanging by a thread, Sam questions who she can trust as her team uncovers information that clouds an already-murky case. And with calls for the president to resign getting louder by the minute, Sam needs to close this case before she finds herself living at 1600 Pennsylvania Avenue.

As a new year dawns in the capital city, dual scandals rock the Metropolitan Police Department—and Lieutenant Sam Holland is right in the middle of them. Chief Farnsworth is catching heat for the way he handled a recent homicide investigation, and Detective Gonzales is accused of failing to disclose an earlier connection to the judge who decided his custody hearing. When Gonzo’s fight for his child turns deadly and he has a shaky alibi, Sam must defend two of her closest colleagues. All while her husband, Vice President Nick Cappuano, settles into his new office at the White House. Nick begins to wonder if the president is using him for a political boost, and his worries mount over a complication in the plans to adopt Scotty at a time when Sam is being put through the wringer by the always-rabid D.C. press corps. As the evidence against Gonzo piles up, Sam suspects someone is gunning for her—and her team.

The phone call that changed their lives forever… Minutes after Vice President Nick Cappuano and Lt. Sam Holland get the call that President Nelson has been found dead in the residence on Thanksgiving, they’re still processing that Nick has been asked to come to the White House to take the oath of office. As they go through the motions to ensure a peaceful transition of power, Sam has a million and one concerns about her husband, her family, the Nelson family, the country and the enormity of what Nick is about to take on. In the back of her mind is another major concern: What does this mean for my job? No other first lady in history has held a job outside the White House, but she’s determined to be the first, to blaze new trails for those who will follow her. However, in order to do that, she quickly realizes that compromises will have to be made to continue working as a Homicide detective. Their lives become an immediate firestorm of meetings, requests for interviews, difficult questions from their children and a host of potential landmines to navigate as they make the transition from second family to first family. An unexpected issue with a diplomatic trip to Iran quickly thrusts Nick into the thick of his new responsibilities while Sam confronts a murder investigation that may have ties to a cold case from fifteen years ago. As everything around them spins out of control, Sam and Nick take refuge with each other, relying on their unbreakable bond to see them through the storm.

Back from their honeymoon, Senator Nick Cappuano and D.C. Police Lieutenant Sam Holland are ready for some normalcy after the whirlwind of their wedding, but someone has other plans for them. When Sam discovers wedding cards containing thinly veiled death threats, she’s not sure if she or Nick is the target. Already on edge, Sam and her team start investigating a series of baffling murders. The victims are well-liked with no known enemies, and the murders are carried out in a clean and efficient manner. Unable to find a clear motive for the deaths, she feels like she’s chasing her tail. With no obvious connection between the victims, Sam soon suspects that she may be the ultimate prize in the killer’s clever game. When the danger starts to hit a little too close to home, she has two goals: find the elusive murderer and manage to live long enough to enjoy her happily ever after.
