A Nurse Called Happy — Peggy Gaddis

Crises at the hospital weren't new to Nurse Happy. Now, in her private life, she faced one she couldn't ignore--and her whole future depended on her decision. And so did the futures of Dr. Norman Hewatt, the handsome surgeon who loved her; Vernon Rustin, wealthy young recluse who also loved Happy and needed her desperately; Janine Kingsley, a raven-haired beauty with cold blooded designs on Vernon.

Happy had no time to think about what was, frighteningly at stake. She had to make her decision fast, and it had to be right.
