Safe Harbor by Kit Kyndall

When Julia witnesses her friend’s murder and is betrayed by one of the marshals meant to protect her, she seeks out Justin Harbor, an old friend of the other marshal, who died protecting her. He’s reluctant to have her at his ranch, but he’ll do his best to keep her safe from the mobster searching for her—and from his personal demons.

She’s determined to get closer to the stubborn ex-soldier and breaks through his walls, but he still maintains an emotional distance between them. When time runs out, and she’s taken, he’ll do anything and risk everything to get her back.
