Silas by Lane Hart

Cora Walsh had no idea how drastically her life would change when a mob boss hired her to cook for him.
After witnessing a bloody massacre, she tries to pretend it was all just a bad dream when she returns to her normal life. That is, until two detectives show up at the restaurant where she works, asking questions about who killed the man who hired her and his four guards.
Scared for her life, and certain she’s being followed, she confesses everything she can remember about the horrible night to the police.
A late-night attack at her home convinces Cora that leaving Carolina Beach behind to start over in witness protection is her only choice.
What Cora doesn’t know is that the tough, no-nonsense FBI agent who swoops in to protect her is not who he says he is.
In fact, he’s the last man she should ever trust.
