Diagnosis Attraction by Rebecca York

While desperately fleeing from the henchmen of a Baltimore mobster, Elizabeth Forester crashes her car into a light pole. She wakes up in the hospital with no memory of who she is. But the moment Doctor Mathew touches her, glimpses of her past come zinging back. Along with the memories, a scorching sexual heat flares between them.
Both Matt and Elizabeth have always felt cut off from normal human relationships. Now she senses she could have what she’s always craved with the handsome doctor.
It’s the same for Matt, although professional ethics dictate that he must not get involved with a patient. But he can’t walk away from the powerful needs drawing them together. After he rescues Elizabeth from a kidnapper, he knows the only way for them to survive is to strengthen the mysterious bond fusing them together.
