Book Description
After her brother dies in a trauma room, nurse Claire Avery can no longer face the ER. She's determined to make a fresh start--new hospital, new career in nursing education--move forward, no turning back. But her plans fall apart when she's called to offer stress counseling for medical staff after a heartbreaking day care center explosion. Worse, she's forced back to the ER, where she clashes with Logan Caldwell, a doctor who believes touchy-feely counseling is a waste of time. He demands his staff be as tough as he is. Yet he finds himself drawn to this nurse educator . . . who just might teach him the true meaning of healing.
