Special Agent Ryan O’Connor’s life is exactly on track—she’s with a wonderful woman, and she’s doing something she loves. Sure, her boss can’t stand her, but she figures if that’s her biggest problem, she’s pretty damn lucky. She should have known it was too good to last and that when fate finally slapped her, it would do so hard enough to leave a mark. When Ryan’s ex-girlfriend, Special Agent Allison Reynolds, suddenly reappears in New York, her carefully constructed world is thrown into chaos. As they’re forced to work together, Ryan is compelled to confront several realities that she wishes she could avoid. One of which is that it’s terrible to mix the past with the present. The other is that it’s not only the past that paints the present with lead.

Following an incident on her last protection assignment, Special Agent Ryan O’Connor’s life is in shambles. Her sort-of ex, Det. Lucia Mendez, was killed, and the guilt she feels is crushing. Her current girlfriend, Special Agent Allison Reynolds, is upset about something, but Ryan doesn’t know what. She’s on light duty because of her own injuries, which severely limits what she’s allowed to do. And what little sleep she’s getting is plagued by horrible nightmares of recent events that confuse as much as terrify her. Ryan tries to put her emotions on the back burner and focus on discovering who was responsible for Lucia’s death, but life keeps derailing her efforts. When Ryan finally manages to get to the bottom of who shot her, she inadvertently discovers the truth will indeed set you free. But not until it’s finished with you. And before it does, it’ll royally piss you off.

Special Agent Ryan O'Connor is starting to get her life back together in the aftermath of a shooting and her boss's arrest. Despite scheduling incompatibilities preventing them from seeing one another, she and Allison are doing great; she's preparing to return to full duty; and she's trying to block out the voices of those who've been doubting she still has what it takes to do her job.Ryan should've known things were never that simple. When a ghost from her past reappears without warning, blindsiding her in a way she never could have expected, Ryan's entire existence is badly shaken. She'd always believed that the best protection any woman could ever have—aside from a gun—was courage, but now she finds herself asking a question she never thought she'd need to answer: Who protects the Secret Service?
