Lost&Found. PASS Series, #4

Even with a degree in psychology and a keen ability to read people, security specialist Bree Graves can't seem to get a bead on her boss. There was a time she thought she had him figured out but she'd been wrong. Still, she loves her job with PASS and her team has become her family. However, she doesn't realize how much she needs them until her latest assignment puts her on the radar of a dangerous stalker. For Yanis Mazur the safety of his PASS team is paramount.
Even if that means sacrificing his personal life. Not only did he spend years building his security firm, but also the shield protecting his emotions. Yet when the one person who could breach his walls goes missing during an assignment he sent her on, he's willing to risk both his business and his heart to get her back. A victim of obsession, betrayal, and violence, Bree has no choice but to put her faith in the man who almost broke her.
