Heart in Waiting — Lynne Collins

Meredith was proud of her place on the hand-picked team of cardiac surgeons at Hartlake, but a new SSO revived too many memories and made no secret of his contempt for her. Rees Falconer was powerfully attractive to women and Meredith had fallen under his spell herself at one time. But that didn't give him the right to treat her as if she was a raw medical student! She soon wondered what she had ever found to like in the arrogant surgeon who seemed determined to punish her for the past.
