Sheltered by the Lawman by Rhonda Lee Carver

Struck over the head, Monica Warren wakes up in the hospital with no recollection of who she is or what happened. The sexy man who has stayed by her side is the only person in the world she knows and she can’t help but cling to him.
Cullen Cade thinks he’s landed the easiest mission he could hope for. Find the missing woman and bring her in. Simple. Then all hell breaks loose when he saves her from a burning building, almost takes a bullet, then learns that she has no memory—not even of who she is or that she is wanted for questioning in the death of her lover. Up until this point in life, Cull has made every decision with his head, but something about the woman, and her situation, tugs at his compassion.
Against better judgement, he offers her shelter, but soon secrets start to unravel as an attraction unlike anything he’s ever felt begins to grow. He struggles to keep his heart protected and stay professional because she is a criminal…isn’t she? What choices will he make that could harm his career? Or break his heart.
An act of mistaken identity, murder, and danger closing in will leave Monica fighting for her memories and her life.
