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.

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?
