Christian Callahan pushed YN away until she finally left him. Now he’s worse than ever—fighting, smoking, barely sleeping, and desperately trying to become someone she might let back into her life. Then he discovers YN has started smoking. She picked up the habit because his cigarettes reminded her of him. At first, it comforted her when she missed him. Now she can’t stop. Christian has always smoked, but he never let YN touch a cigarette. Now he has to watch her become addicted to the same habit he once tried to keep her away from. He wants her back. He wants to help her quit. And this time, he has to learn how to love her without pushing her away.
