Seth by Lynn Raye Harris

Dead to their pasts. Ghosts. No family ties. No connections.

Six men with a top-secret mission move to a small town where they have to navigate local life, protect their secret, and, above all, stay single.
Software engineer Caroline Crowell is a dead woman walking. When the top-secret lab she’s working in goes up in flames and she barely makes it out alive, she knows her time is up. If she wants to stay alive and protect the only family she has left, she has to disappear.
But first she needs help. Someone to watch her back and make sure her enemy doesn’t get any closer while she plans her escape.
Seth “Phantom” King trusts no one but his team. He knows what people are capable of, and he knows how far a person can be pushed before they break. And what he sees when Callie shows up at One Shot Tactical looking for help is a woman about to reach the point of no return.
He doesn’t want to be drawn in by her fear, doesn’t want to believe she’s anything but a potential suspect in his mission. But his teammates have proven that you can’t stop feeling something for a woman even when you know you aren’t supposed to. Denying it only makes it worse.

When the danger Callie fears comes to town, Seth has a choice. Fight for the future he needs. For the woman he needs.
Or watch everything go up in smoke.
