Fifteen years ago, Knox Castillo lost everything when Everleigh Beaumont betrayed him.
The wealthy golden girl and the boy from the wrong side of the tracks had planned a future together-until Everleigh shattered his trust and walked away without explanation. Heartbroken, Knox left town and joined the Marines, determined never to look back.
Now the successful owner of Vantage Security, Knox never expects Everleigh to walk back into his life. Frightened and desperate, she turns to him for help. What begins with anonymous messages and unsettling encounters quickly escalates into something far more dangerous, turning her life into a nightmare. Despite the pain she caused all those years ago, Knox can't bring himself to turn her away.
Pressure builds as Knox and Everleigh are forced to confront both the stalker and the painful past that tore them apart. The deeper they dig, the more Knox questions everything he believed about Everleigh's betrayal-and the harder it becomes to ignore the feelings that never truly died.
In their attempt to unmask the stalker, the investigation takes a dark turn-because the threat is closer than either of them ever imagined.
